Abstract
Provided is a white organic light emitting device and a display apparatus and a lighting apparatus that include the white organic light emitting device. The white organic light emitting device comprises an anode, a hole transport layer, a light emitting layer, an electron transport layer, and a cathode. The light emitting layer includes a red light emitting layer, a blue light emitting layer, and a green light emitting layer sequentially formed from the anode. A functional layer, which blocks an energy transfer and controls electron mobility between the light emitting layers, is formed between the red light emitting layer and the blue light emitting layer or between the blue light emitting layer and the green light emitting layer. The functional layer formed between the red light emitting layer and the blue light emitting layer has a thickness of 50 to 100 Å.
