Abstract: An OLED apparatus that may include a reflection-anode, a transparent-cathode, and a plurality of stacks between the reflection-anode and the transparent-cathode, wherein, among the plurality of stacks, a thickness of the stack disposed relatively close to the transparent-cathode is larger than a thickness of the stack disposed relatively close to the reflection-anode so that it is possible to optimize a micro-cavity of light emitted from the plurality of stacks, thereby improving a light-emission efficiency and a color reproduction ratio and reducing a color change rate in accordance with a viewing angle.
