    摘要： 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.

    摘要： A light emitting element includes a structure in which an anode 51, an organic layer 70 containing an organic material and including a light emitting layer, and a cathode 52 are stacked. The light emitting layer includes, from a side of the anode to a side of the cathode, two or more light emitting regions configured to emit different colors of light. Each light emitting region contains a host material and a dopant material. An absolute value of an ionization potential of the host material contained in a light emitting region near to the cathode is larger than an absolute value of an ionization potential of the host material contained in a light emitting region near to the anode.
