ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a long-life and high-efficiency organic electroluminescent element (an orgnic EL element) which has little change in a color of emitted light even with a long-time drive. SOLUTION: The organic EL element provided with an organic compound case at least having a recombination area where a hole and an electron are recombined and a lumious area emitting light in response to the recombination and a pair of electrodes pinching the organic compound layer contains at least a kind selected from compounds expressed in chemical formula (1) (wherein, each symbol is as defined in the detailed statement) by the ratio of 0.1 to 8 weight percent as a fluorescent dopant at least in either the recombination area or the luminous area.
