FABRICATION METHOD OF ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE

摘要

An organic electro luminescence device is provided to improve the lifetime of the organic electro luminescence device by removing the polymer acting on impurity in the light-emitting layer. A manufacturing method of organic electroluminescent display is composed of the step forming the first electrode(120) on the substrate(110), the step forming the light-emitting layer(133`) including the photodegradation polymer on the first electrode, the step for dissolving the photodegradation polymer included in the light-emitting layer by irradiating the polymer the light-emitting layer, and the step forming the second electrode on the light-emitting layer in which the photodegradation polymer is disassembled. The light irradiated in the light-emitting layer is the ultraviolet ray. The photodegradation polymer is the polymer in which chromophore is included. The light-emitting layer is formed by using the spin coating or the slit coating.
