A liquid crystal display device includes a first liquid crystal display panel in which a first main pixel including subpixels is arranged in a matrix, and that displays a color image, and a second liquid crystal display panel that includes a second main pixel corresponding to a plurality of the first main pixel, and that displays a monochrome image. The second main pixel is divided into a plurality of regions, and has pixel electrodes disposed in the plurality of regions and a plurality of light shields. At least a portion of the plurality of light shields is formed from a switching element that connects to each of the pixel electrodes, and the plurality of light shields is arranged in a staggered manner. The light shields positioned within one set of the regions formed from adjacent regions forms one set of the light shields.

Liquid crystal display device

A liquid crystal display device includes a first liquid crystal display panel that displays a color image, a second liquid crystal display panel that displays a monochrome image, and a display controller that controls the display of the first liquid crystal display panel and the display of the second liquid crystal display panel. The display controller switches the display of the second liquid crystal display panel between a monochrome display that displays a monochrome image and an all-white display. In a state in which the display of the second liquid crystal display panel is the monochrome display, when a response time between predetermined gradations is greater than or equal to a predetermined first response time, the display controller switches the display of the second liquid crystal display panel from the monochrome display to the all-white display.

A driving potential is given to the first electrodes and the third electrodes, respectively. A common potential is given to the second electrodes and the fourth electrodes, respectively. Each of the third electrodes is located at a layer closer to the liquid crystal as compared to the second electrodes, and intersects with one of the second electrodes through an insulating layer. Each of the fourth electrodes is located at a layer closer to the liquid crystal as compared to the first electrodes, and intersects with one of the first electrodes through an insulating layer. A width of the third electrodes is the same as each other at respective intersections of the the third electrodes and the the second electrodes. A width of the fourth electrodes is the same as each other at respective intersections of the the fourth electrodes and the the first electrodes.

To acquire a fine viewing angle property from oblique view fields in a lateral electric field type liquid crystal display device having liquid crystal initial alignment directions in two orthogonal directions. The absorption axis of the incident-side polarization plate and the absorption axis of the exit-side polarization plate are orthogonal to each other in both of the region I and the region II, and the liquid crystal layer, the in-cell retarder as an optical compensation layer, the A-plate, and the C-plate sandwiched therebetween are in parallel to either one of the absorption axes or orthogonal to the substrates. Therefore, the transmittance can be suppressed to be low and a fine black display can be acquired even when the display surface is viewed from the oblique view fields.

Lateral electric field type liquid crystal display device

Provided is a liquid crystal display device and a method for producing the same, wherein one electrode is composed of four segmented electrodes (P, P, P, P) and has segmented orientations (O, O, O, O), and the segmented electrode (p) has the same structure as that of segmented electrodes (P') of adjacent pixels (at three positions of right, below, and lower right). An area surrounding four segmented electrodes (P(P&#x2032;)) that are present in adjacent four pixels having the same structure is processed with the same segmented orientation (O). With this configuration, excellent viewing angle properties are maintained even with high-definition pixels, and efficient processing with segmented orientations can be performed.

The liquid crystal display device includes a transparent electrode formed in a plan form and a strip or strips transparent electrode disposed thereon via an insulating film, and controls display by rotating the liquid crystal aligned substantially in parallel to a substrate within a plane that is substantially in parallel to the substrate by an electric field between the both electrodes. Each pixel constituting the display is divided into two regions, the extending directions of the strip electrode in each of the regions are orthogonal, the alignment azimuths of the liquid crystal of each of the regions are orthogonal, and the angles formed between the extending directions of the strip electrode and the alignment azimuth of the liquid crystal are the same.

A method of fabricating a liquid crystal display device, includes applying an alignment film to a substrate surface, provisionally drying the alignment film, baking the alignment film; rubbing; and rubbing washing, which are performed in this sequence, wherein, in applying the alignment film, the alignment film is formed so as to cover at least a display region, and a portion of the alignment film which extends in a region outside the display region is imparted with an adsorptive property by modification during a process from the provisional drying to the rubbing washing.

In applying an alignment material to surfaces of a CF substrate and a TFT substrate, which form a liquid crystal panel, to form alignment films, an alignment film is formed so as to cover at least a display region in which pixels are arranged in a matrix fashion, while a porous alignment film, which has a porous film structure with a higher impurity adsorptive property than the former alignment film, is formed in a region outside the former alignment film, for example, in a region intermediate the display region and a seal region surrounded by a sealing material, whereby the porous alignment film formed in the region outside the display region can efficiently adsorb contaminants, such as residual impurity ions produced from the sealing material and uncured components of the sealing material, to prevent the contaminants from penetrating into the display region and being fixed therein.

An LCD device is obtained by joining a counter substrate and a TFT substrate with a sealing member having at least a UV-curable characteristic. The sealing member includes a UV-curable resin and high-refractive layers formed respectively on the surfaces of spacers which are dispersed in the UV-curable resin, each of the surfaces of the spacers having a refractive index higher than that of the UV-curable resin.

An LCD device in an LCD projector includes a TFT substrate, a counter substrate, an LC layer sandwiched between the TFT substrate and the counter substrate, and a pair of compensation substrates attached onto the outer surfaces of the TFT substrate and the counter substrate far from the LC layer. The compensation substrate has a negative coefficient of thermal expansion (CTE) for compensating the retardation caused by a temperature rise of the TFT substrate and the counter substrate due to irradiation thereof by a light source.

In a liquid crystal display panel, a gap between an array substrate and an opposing substrate is made constant by using spacers mixed in a seal agent provided around a display area A. A bottom-up pattern formed in the same layer as that of a light shield is formed in a seal area B and a leveling layer on the seal area B is made thinner in order to minimize an amount of sink of the spacers into the leveling layer thereby make the gap between the substrates uniform.
