Abstract: A transparent display device includes a display substrate having a display region and a sealing region surrounding the display region. The display region includes a plurality of pixel regions, each of which includes a light-emitting region and a transparent region. An opposite substrate faces the display substrate. A sealing member is interposed between the display substrate and the opposite substrate. The sealing member overlaps the sealing region. The sealing member bonds the display substrate to the opposite substrate and includes a plurality of first light openings defined therein.

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.
