Organic electroluminescent device and display

Abstract

According to an embodiment of the present invention, there is provided an organic electroluminescent device for emitting red light having an organic layer that includes a light-emitting layer and is provided between an anode and a cathode. The light-emitting layer contains a red light-emitting guest material and a host material that is composed of a polycyclic aromatic hydrocarbon compound having a skeleton with four- to seven-membered rings. Furthermore, a light-enhancing layer that contains a light-emitting guest material for generating light having a wavelength shorter than that of light emitted by the light-emitting layer is provided adjacent to the light-emitting layer.
