Abstract

See full text

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.
