Abstract
An organic EL device is provided which is capable of providing high luminance and high luminous efficiency. In an organic EL device, a hole injecting electrode lies on a glass substrate, and a hole injecting layer, a hole transporting layer, and a light emitting layer are sequentially formed thereon. An electron injecting electrode lies on the light emitting layer. The light emitting layer contains a host material, a light emitting dopant, and a first light-emission assisting dopant. The first light-emission assisting dopant is composed of a rubrene derivative.
