An organic light emitting device and a method for fabricating the same are provided to form a thickness of an organic insulating film of each of subpixel regions corresponding to R, G, and B light emitting layers or R, G, and B color filter layers by using one diffractive exposure mask. An organic light emitting device includes a TFT(Thin-Film Transistor) array substrate, first to third anode electrode(52a-52c), first to third transparent electrodes(55a-55c), organic material layers, an organic insulating film(53), cathode electrodes(62), and an encapsulation substrate(65). A TFT array and first to third subpixel regions are defined on the TFT array substrate. The first to third anode electrodes are formed in the first to third subpixel regions, respectively. The first to third transparent electrodes are in contact with the first to third anode electrodes, respectively. The organic material layer includes first to third light emitting layers(59a-59c) having first to third colors in upper parts corresponding to the first to third subpixel regions. The organic insulating film has different thicknesses in lower parts corresponding to the first to third light emitting layers. The cathode electrodes are formed on the organic material layer. The encapsulation substrate is opposed and bonded to the TFT array substrate. |
