WIPO Patent Application WO/2022/172981
Kind Code:
A1
Abstract:
Provided is a display device for which the complexity of an uneven shape of a formation surface of a semi-transmissive reflection layer can be controlled. This display device comprises: a plurality of first subpixels; a plurality of second subpixels; and a plurality of third subpixels. The first subpixels each comprise a first light-emitting element that emits first light and third light; the second subpixels each comprise a second light-emitting element that emits second light; and the third subpixels each comprise a third light-emitting element that emits first light and third light. The first light-emitting element, the second light-emitting element and the third light-emitting element each comprise: a first electrode; an organic layer including a light-emitting layer; a second electrode; and a semi-transmissive reflection layer. The first electrode and the semi-transmitting reflection layer constitute a resonator structure. The semi-transmissive reflection layer of the first light-emitting element and that of the third light-emitting element have the same height.
