Abstract
A display device having a display surface includes a plurality of black lines defining a plurality of pixels; and a plurality of information patterns arranged so as to overlap the display surface and each representing information regarding a position thereof on the display surface. Each information pattern is formed by using a plurality of marks provided so as to overlap the pixels, and each mark is formed from a material that transmits visible light and absorbs or diffusedly reflects infrared light. A length of each mark in a width direction of the thickest black lines among the black lines defining the pixel overlapped by the mark is larger than a width of each thickest black line.
