Abstract: Provided is a display device including: a substrate; a first light-emitting element over the substrate; and a second light-emitting element located over the substrate and adjacent to the first light-emitting element. Each of the first light-emitting element and the second light-emitting element possesses: a first electrode; an EL layer over the first electrode; a second electrode over the EL layer; and a photochromic layer located over the second electrode and including a photochromic material. The photochromic material is different in chemical structure between the first light-emitting element and the second light-emitting element.

Abstract: A display device according to an embodiment of the present invention includes an anode electrode layer, a cathode electrode layer, a light emitting layer arranged between the anode electrode layer and the cathode electrode layer, a carrier transport layer and a carrier injection layer, which are arranged at least one of between the light emitting layer and the cathode electrode layer or between the light emitting layer and the anode electrode layer and a mixed layer arranged between the carrier transport layer and the carrier injection layer. The mixed layer is formed of a mixture of a material of the carrier transport layer and a material of the carrier injection layer. The mixed layer is formed so that a percentage of the material of the carrier injection layer in the mixture gradually increases in a direction from the carrier transport layer toward the carrier injection layer.
