Liquid crystal display device
View Patent ↗In an IPS mode liquid crystal display device, an interlayer insulating film is formed on a common electrode formed in a planar shape, and a pixel electrode is formed on the interlayer insulating film. The distance between the TFT substrate and the counter substrate is determined by a columnar spacer. The pixel electrode includes one comb-shaped electrode and a contact part. The tip of the comb-shaped electrode overlaps the columnar spacer as seen in a plan view. The columnar spacer is present in the area in which an electric field that allows the liquid crystal molecules to rotate backward occurs when a voltage is applied to the pixel electrode, so that the reverse rotation of the liquid crystal molecules does not occur, and it is possible to prevent the domain from occurring.
1. A liquid crystal display device comprising:
a TFT substrate in which pixels each having a pixel electrode and a TFT are arranged in a matrix form;
a counter substrate; and
a liquid crystal interposed between the TFT substrate and the counter substrate,
wherein in the pixel, an interlayer insulating film is formed on a common electrode formed in a planar shape, and the pixel electrode is formed on the interlayer insulating film, wherein the distance between the TFT substrate and the counter substrate is determined by a columnar spacer,
wherein the pixel electrode includes one comb-shaped electrode and a contact part,
wherein a tip of the comb-shaped electrode overlaps the columnar spacer as seen in a plan view.
2. A liquid crystal display device according to claim 1 ,
wherein the tip of the comb-shaped electrode of the pixel electrode is folded with the width gradually decreasing towards its end.
