Light-emitting element, display element, display device, electronic device, and lighting device
Abstract:
A light-emitting element with high emission efficiency which includes a plurality of light-emitting layers and exhibits multi-color light emission is provided. The light-emitting element includes a first electrode, a second electrode, and an EL layer between the first electrode and the second electrode. The EL layer includes a first injection layer, a first light-emitting layer, and a second light-emitting layer in a first region, and a second injection layer, the first light-emitting layer, and the second light-emitting layer in a second region. The first light-emitting layer includes a first light-emitting material and a first host material, and the second light-emitting layer includes a second light-emitting material and a second host material. A color of light emitted from the first region is different from that of light emitted from the second region.
