ABSTRACT:
An organic electro-luminescence device including an anode, a cathode, an organic light emitting layer and a hole-transporting layer is provided. The cathode has a calcium electrode and an aluminum electrode adjacent thereto. The organic light emitting layer is disposed between the anode and the calcium electrode, and has a polymer, a phosphorescence dopant and an organic electron-transporting material, wherein a ratio of contents of the organic electron-transporting material to contents of the polymer in the organic light emitting layer is substantially between 0.1 and 1. The organic electron-transporting material is 1,3-bis(N,Nt-butyl-phenyl)-1,3,4-oxadiazole. The hole-transporting layer is disposed between the light emitting layer and the anode.
