摘要：
Provided is a white organic light emitting device (OLED), including: a first electrode formed on a substrate; a hole transport layer formed on the first electrode; an emission layer formed on the hole transport layer; an electron transport layer formed on the emission layer; and an color control layer formed on at least one of the hole transport layer, the emission layer and the electron transport layer, and emitting green and/or red by energy transfer from the emission layer. The white OLED emits red, green and blue light with high efficiency, has excellent color reproducibility and a high color reproduction index.
