Organic electroluminescent element |
| abstract |
Provided is a thermally activated delayed fluorescent blue light-emitting organic EL device having high luminous efficiency and a long lifetime. The organic electroluminescent device includes one or more light-emitting layers between an anode and a cathode opposite to each other, wherein at least one of the light-emitting layers contains an indolocarbazole compound represented by the following general formula (1), which serves as a thermally activated delayed fluorescent light-emitting material, and a carbazole compound serving as a host material, and a substituent Ar 2 with which a N atom in the indolocarbazole ring compound is substituted has at least one fluorine atom. |
