ABSTRACT:
An organic EL device in which light-emitting efficiency, color purity and laser induced thermal imaging characteristics are improved by providing with an organic EL device comprising a first electrode, a hole transport layer, a light-emitting layer, and a second electrode, wherein the light-emitting layer uses a mixture of an optically active low molecular electric charge transport material and a high molecular light-emitting substance.
