Abstract
An organic electroluminescent device for emitting red light is disclosed. The device includes: an anode; a cathode; and an organic layer including a light-emitting layer, wherein the light-emitting layer contains a red light-emitting guest material and a host material composed of a polycyclic aromatic hydrocarbon compound having a skeleton with 4 to 7 membered rings, and a photosensitizing layer containing a light-emitting guest material generating green light is provided adjacent to the light-emitting layer.
Claims13
