ORGANIC LIGHT EMITTING DISPLAY

摘要

The objective of the present invention is to provide an organic light emitting display capable of improving lifetime. The organic light emitting display according to the present invention comprises: a first and a second electrode facing each other on a substrate; a charge generation layer formed between the first and the second electrode; a first light emitting stack formed between the charge generation layer and the first electrode; and a second light emitting stack formed between the charge generation layer and the second electrode. A hole injection layer of a light emitting stack implementing a blue color among the first and the second light emitting stack is formed by that a dopant of a hole transportation material less than 0.5%~10% by volume of the hole injection layer is formed as HAT-CN and then is doped in a host.
