Abstract:
1. A method of manufacturing an organic light emitting display device, comprising: forming an anode electrode on a substrate; forming a cathode electrode opposite to the anode electrode; forming a blue common emission layer across each of red, green, blue and white subpixel areas above and adjacent to the anode electrode; forming a green common emission layer across each of red, green, blue and white subpixel areas above the blue common emission layer; forming a red common emission layer across each of red, green, blue and white subpixel areas above the green common emission layer and adjacent to the cathode electrode; and sequentially stacking the blue common emission layer, the green common emission layer and the red common emission layer in a respective order in the white subpixel area without having an intermediate layer, such that a blue light, a green light and a red light are emitted, whereby a white light is output from the white subpixel area.
