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.
