ORGANIC ELECTROLUMINESCENT DEVICE AND MANUFACTURING METHOD THEREOF

摘要

An organic electroluminescent device and a method of manufacture thereof are provided. The device comprises a conductive substrate, a hole-injecting layer, a light-emitting layer, and a cathode layer, which are stacked in order. The material of the hole-injecting layer is made of an acid-doped polyaniline. The polyaniline has good conductivity and high stability, and the polyaniline is suitable as the material of hole-injecting layer. The acid-doped polyaniline can significantly improve the solubility and conductivity. As a result of the acid-doped polyaniline as the hole-injecting layer, the light-emitting performance of the organic electroluminescent device is basically same as a traditional OLED, and the cost is lowered.
