Zusammenfassung:	Disclosed is an OLED apparatus (1000, 2000) that may include a reflection-anode (410, 1410), a transparent cathode (600, 1600), and a plurality of stacks (510, 520, 530, 1510, 1520) between the reflection-anode and the transparent cathode (600, 1600), wherein, among the plurality of stacks (510, 520, 530, 1510, 1520), a thickness of the stack (530, 1520) disposed relatively close to the transparent cathode (600, 1600) is larger than a thickness of the stack (510, 1510) disposed relatively close to the reflection-anode (410, 1410) so that it is possible to optimize a micro-cavity of light emitted from the plurality of stacks (510, 520, 530, 1510, 1520), thereby improving a light-emission efficiency and a color reproduction ratio and reducing a color change rate in accordance with a viewing angle.
