Organic light emitting device

摘要

An organic light emitting device (OLED) including: a substrate (110); a first electrode (210) a second electrode (230) facing the first electrode; a first blue light emitting layer (EML1), a green light emitting layer (EML2), a red light emitting layer (EML3), and a second blue light emitting layer (EML4) all interposed between the first electrode and the second electrode; and a color filter (300) disposed in a path of light emitted from the light emitting layers, wherein the first blue light emitting layer includes a deep blue dopant, and the second blue light emitting layer includes a sky blue dopant.
