Abstract
An organic light emitting display device with enhanced luminous efficiency and color viewing angle and a method of manufacturing the same are disclosed. The method includes forming a first electrode of each of red, green, blue and white sub-pixels on a substrate, forming a white organic common layer on the first electrodes, and forming a second electrode on the white organic common layer, wherein the first electrodes each includes multiple transparent conductive layers and is formed such that a thickness of the first electrode of each of two sub-pixels among the red, green, blue and white sub-pixels is greater than a thickness of the first electrode of each of the other two sub-pixels, and at least two layers excluding the lowermost layer among the multiple transparent conductive layers of each first electrode are formed to cover opposite sides of the lowermost layer.
