摘要:
The present invention provides an organic electroluminescent element which is superior in luminance, reliability, and thermal stability and is capable of selectively emitting light with comparative long wavelengths such as red and good color purity and a light-emitting device or display device incorporated therewith.

摘要:
The present invention provides an organic electroluminescence light emitting device capable of preventing a color (hue) of light and a luminous efficiency from being varied depending on a concentration of a luminous material contained in a light emission layer and an operational condition such as an applied voltage, thereby exhibiting a high luminance, a high performance, and a stable, reliability. The light emitting device includes an anode (6), a hole transport layer (2), a light emission layer (3), an electron transport layer (4), or includes an anode (6), a hole transport layer (2), and a light emission layer (4) serving as an electron transport layer. A light emission region is formed by a mixed layer made from a luminescent material and a charge injection accelerating material. The luminescent material exhibits, in a state held as a single thin film between the anode (6) and the cathode (7), electroluminescence light emission when a DC voltage is applied thereto and has a charge transport characteristic. The charge injection accelerating material is different from the luminous material and has a charge transport characteristic capable of accelerating injection of charges in the luminescent material. The light emission region exists not only at an interface with an adjacent layer or its vicinity but also over a specific thickness region in the layer thickness direction.
