The present invention relates to an organic light emitting device including a first pixel, a second pixel, and a third pixel each displaying a color. Each pixel includes a reflecting member; a transflective member forming a micro-cavity along with the reflecting member; an organic light emitting member disposed between the reflecting member and the transflective member; a transparent electrode disposed between the reflecting member and the transflective member; and a compensation layer disposed between the reflecting member and the transflective member to form a predetermined distance between the reflecting member and the transflective member, wherein the distance between the reflecting member and the transflective member are substantially the same in the first pixel, the second pixel and the third pixel.
