Abstract: A display device has a display area including a first pixel region, a second pixel region, and a third pixel region. The display device includes: a first electrode; a first photoelectric conversion layer including a first light-emitting layer, a second light-emitting layer, and a third light-emitting layer; a first electric charge injection layer; a second electric charge injection layer; a second photoelectric conversion layer including a fourth light-emitting layer; and a second electrode. The first light-emitting layer is provided in the first pixel region. The second light-emitting layer is provided in the second pixel region. The third light-emitting layer is provided in the third pixel region. The first electric charge injection layer is provided across the entire display area. The second electric charge injection layer is provided only in the third pixel region. The fourth light-emitting layer is provided at least in the third pixel region.

Abstract: A display device includes the following: a plurality of first spacers provided at a first pitch that is constant, in a given direction in the display region except where light-emitting elements are provided, the plurality of first spacers having heights that are identical; and n−1 second spacers provided between two of the plurality of first spacers adjacent to each other in the given direction, except where the light-emitting elements are provided, the n−1 second spacers having heights that are smaller than the heights of the plurality of first spacers, where n is a natural number equal to or greater than two. The pitch in the given direction of all spacers including the plurality of first spacers and the n−1 second spacers is a second pitch that is constant, and that is the first pitch divided into n equal parts.
