Techniques for successively fabricating liquid crystal cells at low cost, using two resinous substrates wound on their respective rolls. A color filter and an electrode pattern are formed by printing techniques. Furthermore, an orientation film is printed. These manufacturing steps are carried out successively by rotating various rolls.

Method and system for fabricating liquid crystal cells

The present invention provides an active matrix type display device having a high aperture ratio and a required auxiliary capacitor. A source line and a gate line are overlapped with part of a pixel electrode. This overlapped region functions to be a black matrix. Further, an electrode pattern made of the same material as the pixel electrode is disposed to form the auxiliary capacitor by utilizing the pixel electrode. It allows a required value of auxiliary capacitor to be obtained without dropping the aperture ratio. Also, it allows the electrode pattern to function as a electrically shielding film for suppressing the cross-talk between the source and gate lines and the pixel electrode.

Display device

There is disclosed an active matrix reflective liquid crystal display panel on which an active matrix circuit is integrated with peripheral driver circuits. Metal lines in the peripheral driver circuits are formed simultaneously with pixel electrodes. Thus, neither the process sequence nor the structure is complicated.

A method of manufacturing a semiconductor device, comprises the steps of: forming a first insulating film on a first substrate; forming a second insulating film on the first insulating film; forming an amorphous silicon film on the second insulating film; holding a metal element that promotes the crystallization of silicon in contact with a surface of the amorphous silicon film; crystallizing the amorphous silicon film through a heat treatment to obtain a crystalline silicon film; forming a thin-film transistor using the crystalline silicon film; forming a sealing layer that seals the thin-film transistor; bonding a second substrate having a translucent property to the sealing layer; and removing the first insulating film to peel off the first substrate.

Method of manufacturing a semiconductor device

A pair of substrates forming the active matrix liquid crystal display are fabricated from resinous substrates having transparency and flexibility. A thin-film transistor has a semiconductor film formed on a resinous layer formed on one resinous substrate. The resinous layer is formed to prevent generation of oligomers on the surface of the resinous substrate during formation of the film and to planarize the surface of the resinous substrate.

Semiconductor device having pair of flexible substrates

Regionswhich can be regarded as being monocrystalline are formed locally by irradiating with laser light, and at least the channel-forming regionis constructed using these regions. With thin-film transistors which have such a construction it is possible to obtain characteristics which are similar to those which employ monocrystals. Further, by connecting in parallel a plurality of such thin-film transistors it is possible to obtain characteristics which are effectively equivalent to those of a monocrystalline thin-film transistor in which the channel width has been increased.

Semiconductor device having parallel thin film transistors

An image display system comprises a first liquid crystal projector which projects a counterclockwise-rotating, circularly polarized light beam to form an image containing specific visual information on a screen and a second liquid crystal projector which projects a clockwise-rotating, circularly polarized light beam to form a white image on the same screen. When viewed with the naked eye, a combination of the two images projected on the screen appears totally white. A viewer wearing a dedicated viewing device equipped with an optical filter which allows counterclockwise-rotating, circularly polarized light to pass through can selectively see the image projected by the first liquid crystal projector.

Image display system and method

A laminated spacer portion formed by laminating various thin films that constitute thin-film transistors is disposed in peripheral driver circuits. As a result, even in a structure in which part of a sealing member is disposed above the peripheral driver circuits, pressure exerted from spacers in the sealing member is concentrated on the laminated spacer portion, whereby destruction of a thin-film transistor of the peripheral driver circuits can be prevented caused by the pressure from the sealing portion.
