ORGANIC LIGHT-EMITTING DEVICE

摘要

An organic light-emitting device includes a red emission layer formed by mixing a first host made of a carbazole-based material, a second host made of a metal complex and a dopant. Accordingly, the driving voltage of the organic light-emitting device can be reduced, and thus power consumption of the organic light-emitting device can be improved. In addition, by mixing the first host and the second host having differences in energy level in the red emission layer, the luminous efficiency of the red emission layer of the organic light-emitting device can be improved. Thus, the lifetime of the organic light-emitting device can be elongated.

主权项

1. An organic light-emitting device, comprising:
a first electrode and a second electrode; and an emission layer disposed between the first electrode and the second electrode over a plurality of sub-pixel regions, the emission layer comprising a red emission layer, a green emission layer and a blue emission layer, wherein the red emission layer comprises a first host, a second host and a dopant, wherein the first host is made of a carbazole-based material, and the second host is made of a metal complex.
