Claim:
1. A method of manufacturing an organic light emitting display device, comprising: forming a first electrode over a substrate in which red, green, and blue pixel areas are defined; forming a first hole transporting layer on the first electrode; forming a second hole transporting layer on the first hole transporting layer in a position corresponding to the red pixel area; forming a first emission common layer on the second hole transporting layer and the first hole transporting layer in respective positions corresponding to the green and blue pixel areas; forming a third hole transporting layer on the first emission common layer in a position corresponding to the green pixel area; forming a second emission common layer on the third hole transporting layer and the first emission common layer in respective positions corresponding to the red and blue pixel areas; forming a fourth hole transporting layer on the second emission common layer in a position corresponding to the blue pixel area; forming a third emission common layer on the fourth hole transporting layer and the second emission common layer in respective positions corresponding to the red and green pixel areas; forming an electron transporting layer on the third emission common layer; and forming a second electrode on the electron transporting layer.
