Abstract:
1. A light-emitting device comprising: a first electrode; a hole-transport layer over the first electrode, the hole-transport layer comprising a first organic compound; a first light-emitting layer over the hole-transport layer, the first light-emitting layer comprising a first phosphorescent compound which is configured to emit one of green light or orange light and a second organic compound; a second light-emitting layer over the first light-emitting layer, the second light-emitting layer comprising a second phosphorescent compound which is configured to emit the other of green light or orange light and a third organic compound; a third light-emitting layer over the second light-emitting layer, the third light-emitting layer comprising a fluorescent compound which is configured to emit blue light and a fourth organic compound; an electron-transport layer over the third light-emitting layer, the electron-transport layer comprising a fifth organic compound; and a second electrode over the electron-transport layer.
