Abstract: An organic light emitting display device includes a substrate comprising a display area and a peripheral area and a first reflective member positioned in both the display area and the peripheral area. The first reflective member includes a first opening formed in a light-emitting region of the display area and a second opening formed in the peripheral area. The second reflective portion has openings having the same shape as openings formed in the first reflective portion. Thus, a reflectivity of the first reflective portion may be substantially the same as a reflectivity of the second reflective portion, and the first reflective portion and the second reflective portion may be perceived as an integral reflective member. Therefore, a bezel-less mirror organic light emitting display device may be manufactured.
