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： A liquid crystal display device includes a thin film transistor (TFT) array substrate 10, a counter substrate 22 provided opposite to the TFT array substrate 10 and a liquid crystal layer 28 held between the TFT array and counter substrates 10 and 22. The TFT array substrate 10 has display and frame areas 31 and 32. There are pixel electrodes in the display area 31 which each have reflective and transparent portions 33 and 34 with convex and concave portions 29 and 30, respectively. Convex and concave portions 36 and 37 are also provided in the frame area 32 which are substantially the same in shape as convex and concave portions 29 and 30 in the display area 31. The surface of a photoresist coating film in the display area 31 shown by a dotted line 39 is substantially the same in configuration as that in the frame area 32 to make the column-like spacers 27 and 38 substantially the same in height. A cell gap between the TFT array and counter substrates 10 and 22 is made thereby substantially uniform.

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 coupling line connecting a pixel electrode to a source electrode and a storage capacitance electrode includes a wiring portion which does not overlap a storage capacitance line or a storage capacitance electrode. Thus, the wiring portion is exposed when viewed from the rear side of the array substrate. Therefore, even if a short circuit occurs between the storage capacitance line and the coupling line or the storage capacitance electrode, a pixel including the short-circuit defect can be improved to a half-lighted state by radiating the laser beam to the wiring portion to electrically cut it.

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： A liquid crystal display panel is arranged such that a reflection member overlaps a light-shielding wiring pattern such that apertures are left unmasked. This prevents light use efficiency from being decreased due to a light-shielding wiring pattern having memory wiring layers. An array substrate includes a transparent electrode which applies a field to a liquid crystal layer, a light-shielding wiring pattern having one or more apertures which allow transmission of light incident on the liquid crystal layer from the reverse side of the array substrate, and a reflection member which reflects incident light applied from a counter substrate side through the liquid crystal layer.

摘要： A liquid crystal display device includes a driving voltage supply line connected to a transfer pad through a contact hole. The contact hole is corroded under the open air in a prior art liquid crystal display device. According to the present invention, however, the contact hole is provided in an air tight place ranging from an edge portion of a display area through a sealing material, e.g., underneath the sealing material. With this structure the contact hole is not exposed to the open air so that its resistance to corrosion is significantly improved.
