In this work, we report top emission white OLED (TE-WOLED) device for an application to large sized and high resolution OLED TV. Like as bottom emission device, we adopted 3 stack WOLED consisting of two blue and one yellow green (YG) light-emitting units with a reflective metal as the bottom anode and a transparent compound as the top cathode. By using an optical simulation, we designed the device structure and found optimum positions for EML with consideration of viewing angle property. As a result, we demonstrate top emission white OLED comparable to bottom emission OLED, regarding efficiency, operating voltage and viewing angle.
