| 20110006288 | ORGANIC LUMINESCENT DEVICE AND MANUFACTURING METHOD THEREOF - There is provided a polymer or low-molecular-weight compound multilayer type organic EL device configured such that a light-emitting layer formed on a hole transport layer includes a mixture of a polymer material and a low-molecular weight material. With such a configuration, the low-molecular-weight material added to the polymer material serves as a binder filling the gap of the steric hindrance to form entanglement of the polymer material and the low-molecular-weight material. This results in that the interface between the hole transport layer and the light-emitting layer is an interface high in adhesion and also high in carrier injectability. Further, optimization of the formation conditions and materials can achieve still higher reliability and longer lifetime. | 01-13-2011 |
