Abstract: Provided are a method of manufacturing an organic light emitting display device and an organic light emitting display device manufactured by the method. The method includes calculating a peak-luminance current density for each of a red sub-pixel, a blue sub-pixel, a green sub-pixel, and a white sub-pixel, calculating an average use current density for each of the red sub-pixel, blue sub-pixel, green sub-pixel, and white sub-pixel; determining a size of each sub-pixel with the peak-luminance current density and the average use current density, and forming the sub-pixels with the determined sizes of the respective sub-pixels. The present invention sets the size of each sub-pixel in consideration of a peak-luminance current density and an average use current density, thus easily achieving the peak luminance and enhancing the color-coordinate life.
