A top emitting organic light emitting diode and a preparation method thereof, comprising a substrate sequentially stacked anode layer (101), (102), a hole injection layer (103), a hole transport layer (104), light emitting layer (105) and electron transport layer (106), the electron injection layer (107) and Yin the electrode layer (108); a cathode layer (108) arranged in the electron injection layer (107) on the aluminum layer (1081) disposed in the aluminum layer (1081) mixed layer consisting of silver and silicon oxide (1082). Because the cathode layer (108) adopts a composite layer structure composed of an aluminum layer (1081) and a mixed film layer (1082), the light transmittance of the device is improved, so that the luminous efficiency of the device is improved.
