Patent ID: 10873057

Abstract:
An electroluminescence display includes a substrate, a bank defining a first light emitting area, a second light emitting area, and a third light emitting area on the substrate, a first light emitting layer provided in the first light emitting area, a second light emitting layer provided in the second light emitting area, a third light emitting layer provided in the third light emitting area, and a fourth light emitting layer provided on the first light emitting layer, the second light emitting layer, the third light emitting layer, and the bank, wherein the fourth light emitting layer emits light having the same color light of the third light emitting layer. If red light is emitted from the first light emitting layer, green light is emitted from the second light emitting layer, and blue light is emitted from the third light emitting layer and the fourth light emitting layer, the luminous efficiency of blue light can be improved.
