摘要： A liquid crystal display device using columnar spacers to eliminate an influence of shades in rubbing an orientation film and to eliminate remaining of display unevenness (black haze) in black display is provided. Columnar spacers are provided above a black matrix of an opposite substrate disposed opposite to a TFT substrate. A position of a top of each columnar spacer in contact with the TFT substrate is shifted from a center of a gate line of the TFT substrate toward a common line parallel to the gate line. Moreover, a structure is adopted, in which the top of the columnar spacer contacting with the TFT substrate is not entirely brought into contact with the TFT substrate, but a gap is provided between a part of the top of the columnar spacer and the TFT substrate by providing an irregular surface on the top of the columnar spacer or the like. This gap can reduce frictional force between the top of the columnar spacer and the TFT substrate to result in restricting an occurrence of the black haze when external force is applied to a screen of the liquid crystal display device.

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 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.

摘要： A pixel electrode connected to a signal line through a switching element and a common electrode connected to a common wiring are disposed, as alternating with each other, within each pixel region. Common potential lines are disposed on level below the signal line with an insulating film in between and also on both sides of the signal line when seen in plan view. A floating electrode is disposed on level above the signal line with a protective film in between, as overlapping the signal line and the common potential lines on both sides of the signal line.
