摘要 |
<p>Provided is a practically useful organic electroluminescent device (organic EL device) having high efficiency and high driving stability while being capable of being driven at a low voltage. The organic electroluminescent device includes a light-emitting layer between an anode and a cathode opposite to each other. The light-emitting layer contains two host materials and at least one light-emitting dopant. One of the two host materials is a host material selected from an indolocarbazole compound having one indolocarbazole ring and an indolocarbazole compound having two indolocarbazole rings, and the other thereof is a host material selected from carbazole compounds.</p> |
