A display panel includes sub-pixel pairs arranged laterally at a predetermined pitch, the sub-pixel pair including two sub pixels displaying images for right and left eyes respectively. A parallax-barrier shutter panel includes sub apertures switching light-transmitting and light-blocking states by driving a liquid crystal layer held between two transparent substrates with transparent electrodes extending vertically. The sub apertures are arranged laterally at a pitch obtained by dividing a reference parallax-barrier pitch by N (N being an even number equal to or greater than four), the reference parallax-barrier pitch being determined on the basis of a predetermined design observation distance and the pitch of the sub-pixel pairs. The parallax-barrier shutter panel includes common driving areas obtained by dividing a display area laterally. (N&#xb7;M+N/2) pieces of the transparent electrodes (M being a positive integer) arranged in the common driving are connected with every N-th one of the transparent electrodes.

Stereoscopic image display apparatus, and drive method therefor

Each pixel of a multiple view liquid crystal display in a normally black mode includes a counter electrode provided with a slit for generating a fringe electric field. An alignment film subjected to liquid crystal alignment processing in a predetermined direction is disposed on a surface of a TFT substrate provided with the counter electrode. An angle formed by an extending direction of a slit at an end of a pixel region (a first region) and a direction of the liquid crystal alignment processing is greater than an angle formed by the extending direction of the slit in a central part of the pixel region (a second region) and the direction of the liquid crystal alignment processing. The first region has a higher transmittance than that in the second region when low luminance display is carried out.

Multiple view liquid crystal display

A liquid crystal display apparatus includes: an array substrate; a seal material; and an opposite substrate, wherein the array substrate includes: a plurality of thin film transistors formed in correspondence to respective intersection parts of a plurality of gate wirings and a plurality of source wirings; a pixel electrode connected to the thin film transistor; an opposite electrode formed to face the pixel electrode; a gate extraction wiring that connects the gate wirings and a connection terminal formed in an outer area of the seal material; a conductive film that covers the gate extraction wiring with sandwiching a first insulation film therebetween; and a second insulation film that covers the conductive film in at least part of the outer area of the seal material, and wherein the conductive film is applied with an electrical potential of the opposite electrode.

Liquid crystal display apparatus

The display device includes a display panel on which sub-pixel pairs are arranged in a lateral direction, and a parallax barrier shutter panel on which sub-openings that can be changed between a light transmittance state and a light-shielding state are arranged in a lateral direction. Arbitrary allocated number of adjacent sub-openings among the plural sub-openings belonging to a reference parallax barrier pitch are put into a light transmittance state, and the remaining sub-openings are put into a light-shielding state, so that a general opening is formed on the parallax barrier shutter panel. A sub-opening pitch of the sub-opening on the boundary part between the adjacent common driving areas is different from the sub-opening pitch of the other sub-openings.

Display device

Only a first pixel electrode exists just under a first light shielding part of a black matrix, a gate insulating film and an interlayer insulating film exist on the upper layer of the first pixel electrode, and this area is an end area. Just under an opening of the black matrix, a second pixel electrode exists on the uppermost layer of a TFT substrate. The second pixel electrode is formed on the gate insulating film and the interlayer insulating film except a contact part. An area where the second pixel electrode exists on the uppermost layer of the TFT substrate is a main area. By a combination structure of the first pixel electrode and the second pixel electrode, the transmittance of the liquid crystal layer in the end area is made relatively higher than the transmittance in the main area.

Liquid crystal display device

A one-pixel structure of a display panel included in an auto-stereoscopic image display device adopts an in-plane switching mode. Transparent counter electrodes that are not provided in a liquid crystal panel of a normal in-plane switching mode are formed correspondingly to pixel peripheral regions on a second transparent substrate side and, in 3-dimensional image display, a vertical electric field is forcibly generated between the transparent counter electrodes and the comb-shaped electrodes, which causes the liquid crystal molecules to rise to show black display in the pixel peripheral regions. In 2-dimensional image display, meanwhile, the transparent counter electrodes are set to be floating, and the display panel is caused to have a structure substantially equivalent to a structure in which the transparent counter electrodes are not provided, to thereby make the display in pixel peripheral regions identical to the display (brightness) in a pixel main region.

A liquid crystal display panel includes signal lines, scanning lines, a common line, and a planarizing film covering the lines. Pattern edge portions of a pixel electrode are arranged to be overlaid above edge portions of the signal lines and the scanning lines. Further, slits being openings formed at the pixel electrode are formed line-symmetrically to each other relative to a reference line which is the extending direction of the common line arranged to cross the center portion of a pixel part.

On a wiring conversion part connected to a first conductive film and a second conductive film each functioning as a wiring, a hollow portion is formed inside the second conductive film. A first transparent conductive film provided on the second conductive film is formed so as to cover an upper surface of the second conductive film and an end surface thereof exposed on the hollow portion, and so as not to cover an outer peripheral end surface of the second conductive film. A second transparent conductive film which is a layer above the first transparent conductive film is connected to the second conductive film and the first conductive film, so that the first conductive film and the second conductive film are electrically connected.

A pixel of a liquid crystal display device includes a scan line, a signal line, a TFT, a lower electrode, and an upper electrode arranged thereon with a protection film interposed therebetween, in which the upper electrode includes a plurality of branch electrode parts electrically connected in common, and a gap part between the branch electrode parts. The upper electrode includes a region in which a ratio of a width of the gap part to a width of the branch electrode part that is adjacent to the gap part is different, and includes both of a region in which a light transmittance increases and a region in which the light transmittance decreases with respect to a change in the ratio.

A liquid crystal display apparatus according to the invention is an in-plane switching liquid crystal display apparatus having gate wirings and source wirings, which intersect one another, and also having pixel electrodes each connected to an associated one of the source wirings, and common electrodes disposed opposite to the pixel electrodes. A scanning signal is inputted to the gate wiring so that one horizontal period has a writing period, in which a pixel potential is written to the pixel electrode, and a nonwriting period, in which no pixel potential is written to the pixel electrode. The pixel potential is outputted to the source wiring in the writing period, while a common potential is inputted to the source wiring in the nonwriting period.

A second transparent conductive film as an upper layer of the first transparent conductive film is connected to the first conductive film and the second conductive film, so that the first conductive film and the second conductive film are electrically connected.
