Abstract:
An organic EL device which includes a first electrode, a hole transport layer, a light-emitting layer, and the second electrode, wherein the light-emitting layer includes a mixed light-emitting film of a host substance, which is capable of transferring an energy to another light-emitting polymer by absorbing the energy, and a phosphorescent dopant which is capable of emitting light using a triplet state after absorbing the energy received. Accordingly, the light-emitting layer can be patterned, and a color purity and light-emitting characteristics of a full color organic polymer EL device, produced through a laser induced thermal imaging operating, can be improved.
