摘要： In a liquid crystal display unit where a matrix pattern of pixels are defined by gate lines and crosswise data lines, transparent pixel electrodes are formed on the same layer as the data lines and corresponding transparent common electrodes are formed above the transparent pixel electrodes. On the common electrodes the liquid crystal layer is provided. In the aperture of each pixel, the common electrode has a pattern of parallel stripe portions and a peripheral portion outside of the aperture for shielding the field of the corresponding data line. Each pixel electrode cooperates with that parallel stripe portions of the corresponding common electrode to produce inner fringe fields along such parallel stripe portions and has portions that overlap the peripheral portions of the common electrode to produce peripheral fringe fields so that liquid-crystal cells can be uniformly in-plane switched by the inner fringe fields as well as by the peripheral fringe fields.

摘要： Disclosed is an active matrix liquid crystal display device including substrates and a liquid crystal layer. The substrate includes: scan signal wiring lines; common signal wiring lines; video signal wiring lines intersecting these wiring lines; and pixels surrounded with the scan signal wiring lines and the video signal wiring lines. Each of pixels includes: a thin film transistor; source electrodes in a layer with the video signal wiring lines; pixel electrodes connected to the source electrodes; and common electrodes connected to the common signal wiring lines. The source electrodes include first parts overlapping the scan signal wiring lines and second parts connecting with the pixel electrodes, which are positioned around central parts between the video signal wiring lines. Molecular axes in the liquid crystal layer rotate under an electric field applied between the pixel electrodes and the common electrodes.

摘要： Disclosed is a liquid crystal display device that includes a TFT substrate. A plurality of gate lines and a plurality of common lines extend in a first direction on the TFT substrate. Drain lines extend in a second direction substantially perpendicularly to these lines. Bus lines are located outside a display area and are extending parallel to the drain lines. Common line terminals are provided on either side of each block that is constituted by a predetermined number of gate terminals. The common line terminals and the lead lines therefor are formed on the same layer as the drain lines and are connected to the bus lines on the same layer without any contacts being used. Resistance along the routes taken by common lines can be reduced.
