Abstract:
1. A display device comprising: a plurality of pixels for displaying an image; a plurality of light receiving sensors for detecting light, the plurality of light receiving sensors being arranged among the plurality of pixels; and a plurality of dummy black portions being covered with black masks or having no light receiving sensor, the plurality of dummy black portions being arranged among the plurality of pixels, wherein when a portion including the pixel is made a light portion, and each of a portion inducing the light receiving sensor and a portion including the dummy black portion is made a dark portion, wherein the light portion and the dark portion are disposed in a repetitive pattern, wherein a light receiving sensor pitch of the plurality of light receiving sensors is greater than a pixel pitch of the plurality of pixels, wherein the plurality of light receiving sensors and the plurality of dummy black portions are arranged so as to satisfy a conditional expression y=nxα in which y is an interval between the adjacent two light receiving sensors, n is a natural number, and α is an interval between the adjacent two dark portions, and wherein the plurality of pixels, the plurality of light receiving sensors, and the plurality of dummy black portions are disposed such that a spatial frequency of the repetitive pattern becomes equal to or higher than 10 cpd.
