摘要： A liquid crystal display device has an array substrate and an opposite substrate arranged opposite to each other through a plurality of columnar spacers with a liquid crystal layer sandwiched therebetween. A plurality of wiring lines and coloring layers are provided over the array electrode. A frame pattern is formed on the array substrate at the outer side of the display area to prevent a light leakage at the outer peripheral edge of the display area. The frame pattern is so provided as to have a gap relative to the outermost peripheral side columnar spacers. At a gap between the frame pattern and the outermost peripheral side columnar spacers, a wiring line is provided with its portion formed in an overlapping relation to the frame pattern, thus blocking light.

摘要： A reflector has protuberances and recesses in each pixel region. The distances between the respective peaks of each two adjacent protuberances in the pixel region are distributed in the range from 5 μm to 15 μm. The incidence of peak distances within the range of ±0.5 μm from the most frequent peak distance ranges from 40% to 80%, and the area of regular reflection surfaces of the reflector tilted at angles of 4.5° or less to the principal surface of a substrate in the pixel region accounts for 35% or less of the area of the pixel region.

摘要： To manufacture an active-matrix substrate, a metal film is formed on a glass substrate. The metal film has a first region and a second region, which lie between other regions of the metal film that will be gate lines and auxiliary capacitance lines. The first and second regions are removed in a process of making, in the metal film, through holes achieving ion doping. Thereafter, the metal film including the first and second regions is patterned, thereby forming gate lines and auxiliary capacitance lines. Hence, the first and second regions of the metal film are etched twice, without increasing the number of steps of manufacturing the active-matrix substrate. The probability of short-circuiting between any gate line and the adjacent auxiliary capacitance line is therefore low.

摘要： A signal line driving circuit makes the polarities of video signals different from each other, the video signal being supplied to pixel electrodes adjacent to an arbitrary pixel electrode on both sides thereof in a horizontal scanning direction. The signal line driving circuit also makes the polarities of video signals different from each other, the video signal being supplied to pixel electrodes adjacent to the arbitrary pixel electrode on both sides thereof in a vertical scanning direction. A signal line driving IC outputs the video signal to each signal line group obtained by dividing a plurality of signal lines to a plurality of signal line groups composed of a predetermined number of the signal lines. A signal line switching circuit switches all of the signal lines in each signal line group sequentially during one horizontal scanning period.

摘要： Each pixel electrode is connected to a signal line and a scanning line through a TFT while at least part thereof overlaps the signal lines. A plurality of shield electrodes having electrostatic shielding characteristic extend from an auxiliary capacitance line, which extends perpendicular to the signal lines, each along the signal line. Each shield electrode has a first electrode portion arranged to overlap only a side edge portion of one of two adjacent pixel electrodes and a side edge portion on a side of one pixel electrode of the signal line side edge portions, and a second electrode portion arranged to overlap only a side edge portion on the other pixel electrode. An overlapping width between the shield electrode and pixel electrode is larger than the overlapping width between the signal line and pixel electrode.

摘要： Not only a signal line (27a) but also an adjacent signal line (27b) partly oppose a reflection pixel electrode (50a) through an insulating film to be capacitively coupled to the electrode. The area of that portion (27a1) of the signal line (27a) which opposes the reflection pixel electrode (50a) is almost equal to that of that portion (27b2) of the signal line (27b) which oppose the pixel electrode (50a). Therefore, the influence of the signal potential of the signal line (27a) on the reflection pixel electrode (50a) through capacitive coupling is nearly equal to that of the signal potential of the signal line (27b) on the reflection pixel electrode (50a) through capacitive coupling. Luminance differences between adjacent pixels (50a and 50b; 50b and 50c, . . . ) are reduced, thereby preventing crosstalk.
摘要翻译：不仅信号线（27a），而且邻近的信号线（27b）部分地通过绝缘膜与反射像素电极（50a）相对电容耦合到电极。与反射像素电极（50a）相对的信号线（27a）的部分（27a1）的面积大致等于与像素电极（50a）相对的信号线（27b）的部分（27b2）的面积，。因此，通过电容耦合，信号线（27a）的信号电位对反射像素电极（50a）的影响与反射像素电极（50a）上的信号线（27b）的信号电位的影响几乎相等，通过电容耦合。相邻像素（50a和50b; 50b和50c之间的亮度差）减小，从而防止串扰。
