ORGANIC LIGHT EMITTING DEVICE

摘要

The present invention relates to an organic light emitting device capable of emitting white light by including an anode, a cathode, and a plurality of stacks which are formed between the anode and the cathode and emit light with different colors. The plurality of stacks include a stack which emits blue light and a stack which emits mixed light with the blue light and yellowish green light or red light. The organic light emitting device according to the present invention entirely improves luminous efficiency by emitting the blue light with relatively low efficiency from two stacks by including the stack which emits the blue light and the stack which emits the mixed light with the blue light and the yellowish green light or the red light.
