摘要：
The present invention provides an organic EL device utilizing phosphorescence which can be driven at a low voltage, which realizes high luminance and high efficiency, and which has a long lifetime. The organic EL device of the present invention includes an organic light-emitting layer composed of at least a host material and a dopant, wherein the dopant is a phosphorescent compound containing a halogen atom, and the host material is a linear aromatic compound having no aromatic substituent at a side thereof.
