Provided is a practically useful organic electroluminescent device (organic EL device) having a low voltage and high efficiency and high driving stability. This organic electroluminescent element includes a light emitting layer between an anode and a cathode facing each other, the light emitting layer contains two host materials and at least one light emitting dopant, and one of the two host materials is indolo. The host material is selected from an indolocarbazole compound having one carbazole ring or an indolocarbazole compound having two indolocarbazole rings, and the other is a host material selected from carbazole compounds. |
