ORGANIC FIELD LIGHT EMITTING ELEMENT

摘要

An organic field light emitting element in which the light take out efficiency, electrical characteristics, lifetime, and the like, of the element are enhanced. An organic field light emitting element which can inject and transport both positive and negative charges and can emit light through recombination of holes and electrons generated by both positive and negative charges and having a light emitting layer containing a recombined light emitting substance contained in the organic field light emitting element or a fluorescent substance which can emit secondary light upon receiving light from the light emitting substance, characterized in that, a first class intermediate layer is provided between an interface for taking out light to the outside of the organic field light emitting element and the outside of the light emitting layer and the intensity orientation distribution of light taken out from the light emitting layer is enlarged after passing through the first class intermediate layer.
