Top-emitting organic electroluminescent device and manufacturing method thereof

A top-emitting organic electroluminescent device and a manufacturing method thereof are provided. The device comprises a substrate (101), an anode layer (102), a hole-injecting layer (103), a hole-transporting layer (104), a light-emitting layer (105), an electron-transporting layer (106), an electron-injecting layer (107), and a cathode layer (108), which are stacked in order. The cathode layer (108) comprises an aluminum layer (1081) and a composite thin film (1082), which consists of Ag and SiO. The aluminum layer (1081) is deposited on the electron-injecting layer (107), and the composite thin film (1082) is deposited on the aluminum layer (1081). The cathode layer (108) has a composite-layer structure consisting of the Ag and the SiO, so the light transmittance of the device is enhanced, and the emission efficiency of the device can be improved.
