Abstract: A display device has a plurality of color filters and a first light-shielding film formed in a matrix so as to partition a pixel. The plurality of color filters includes: a first color filter selectively transmitting blue light; a second color filter selectively transmitting green light; and a third color filter selectively transmitting red light. The first color filter has a plurality of island-shaped patterns arranged apart from each other along a Y direction intersecting with an X direction. In a plan view, an optical sensor is arranged at a position overlapping with a region between the plurality of island-shaped patterns adjacent to each other. The region has a first opening that is covered with the first light-shielding film and is formed at a position overlapping with optical sensor, the first opening passing through the first light-shielding film.

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.
