发明名称 ORGANIC ELECTROLUMINESCENT ELEMENT
摘要 An organic electroluminescent element having at least an anode, a cathode, and a light-emitting layer held between the anode and the cathode on a substrate and emitting white light. The light-emitting layer consists of three or less layers, the light-emitting material contained entirely in the light-emitting layer consists of at least four kinds of light-emitting material having different emission maximum wavelengths (λmax). The four kinds of light emitting material have emission colors of blue, green, yellow red and red, and since one or more layers out of the three or less layers of the light-emitting layer contain two or more kinds of light-emitting material simultaneously, there is obtained an organic electroluminescent element excellent in color rendering and exhibiting high power efficiency in which variation in emission color is small even if current density varies.
