ORGANIC LIGHT EMITTING DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME
First Claim
1. A method of manufacturing an organic light emitting display device, the method comprising:
- 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 comprises multiple transparent conductive layers and are 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 that of the first electrode of each of the other two sub-pixels, andat least two layers excluding the lowermost layer among the multiple transparent conductive layers of the first electrodes are formed to cover opposite sides of the lowermost layer.

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.
