Abstract
An OLED display device and a method for manufacturing the OLED display device are provided. The OLED display device comprises a substrate, a first electrode disposed on the substrate, a hole injection layer disposed on the first electrode, an organic light emitting layer disposed on the hole injection layer, an electron injection layer disposed on the organic light emitting layer, and a second electrode disposed on the electron injection layer. A material of the electron injection layer comprises an inorganic electron injecting material and an organic electron transporting material which can be dissolved in a polar solvent. The OLED display device and the method for manufacturing the OLED display device can effectively improve the electron injection efficiency for providing an excellent electron injection effect through the electron injection layer is prepared by a solution in which the inorganic salt material and the organic material were mixed.
