ORGANIC ELECTRICAL FIELD LIGHT-EMITTING ELEMENT

摘要

Provided is a practically useful organic EL element having high efficiency and high driving stability while being capable of being driven at a low voltage. The organic EL element has a light-emitting layer and any other organic layer between an anode and a cathode opposite to each other. The light-emitting layer contains at least two host materials and at least one light-emitting dopant. At least one of the host materials is a host material selected from compounds each having one or two indolocarbazole skeletons, and at least one of the other host materials is a host material selected from carbazole compounds each substituted with a dibenzofuran or a dibenzothiophene.
