Abstract
A display device includes: a display panel including display elements each including a light emitting unit and a drive circuit for driving the light emitting unit, the display elements being arranged in a two-dimensional matrix on a substrate; and a luminance correction unit for correcting luminances of the display elements in display of an image by the display panel by correcting a gradation value of a video signal, in which a partition (60) for guiding stray light from a light emitting unit to an optical sensor (4) provided on the display panel is provided between adjacent light emitting units of the display panel, and the luminance correction unit corrects a gradation value of a video signal associated with each of the display elements on the basis of a gradation value of an uncorrected video signal and a detection result from the optical sensor.
