摘要： In a large-sized liquid crystal display panel formed through multiple time exposure using a single mask, the storage capacity between a gate and a source of TFT is adjusted by making an offset for exposure at the exposure connecting portion to decrease variations in the feedthrough voltage in a screen. Further, by preparing the layout of an exposure mask such that the overlap area between a gate signal wire or a storage wire and a pixel electrode is made smaller the farther the overlap area is from a gate signal input part. By making the overlap area smaller, the storage capacity is made smaller, which decreases the variation of the feedthrough voltage in the single exposure area.

摘要： A lighting apparatus for illuminating a liquid crystal display (LCD) panel from behind is disclosed, wherein the LCD panel, when illuminated uniformly, exhibits asymmetric contrast ratios as viewed in a vertical direction. The apparatus comprises a light guide panel having a multitude of light reflecting dots on a reflecting surface opposite to the LCD panel, and a light source for injecting light into the light guide panel in a horizontal direction through a first edge of the light guide panel, so that the light propagates through the light guide panel toward the opposite edge of the panel and irregularly reflects off the dots toward the liquid crystal display panel. The light reflecting dots in a lower portion of the reflecting surface have a lower density than those in an upper portion of the reflecting surface, and each of these portions of the reflecting surface has a density increasing as a function of distance from the first edge of the light guide panel so that the LCD panel has equal brightness at the upper and lower portions when viewed at an angle substantially equal to 90.degree. and an angle smaller than 90.degree., respectively.

摘要： The active matrix type liquid crystal display device has a plurality of liquid crystal elements. Each liquid crystal element has a transistor section, a transistor side conductive light shielding film electrically connected to the transistor section, and a liquid crystal element having an opposing electrode coupled to the transistor section. There are a first potential terminal connected to the opposing electrode and a second potential terminal connected to the transistor side conductive light shielding film with a potential applied by the first potential terminal being independent from a potential applied by the second potential terminal. With this arrangement, the lateral field components around the pixel portion, which become a cause for the reverse tilt of the liquid crystal, are relatively reduced with respect to the vertical field components, thus reducing the disclination and providing excellent display characteristics without residual images.
