Abstract: 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 spaces. 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.
