An OLED device comprises an anode, a hole transport layer, a luminance layer, an electron transport layer and a cathode. Molecules of film materials of forming the carrier transport layer all stand upright on the electrodes. A long axis of the molecule is perpendicular to the electrodes. There forms vertical conjugated planes between the molecules of each molecule layer in the film. These conjugated planes are parallel to each other and perpendicular to the electrodes. Therefore, the carrier transportation of the OLED device of the present invention mainly relies on the conjugated bonds in the molecules, but not the transition between the molecules, thereby efficiently improving the carrier mobility, reducing the working pressure and the power consumption of the OLED device, and improving the performance of the OLED device. |
