Abstract: A transparent display panel and a transparent display device including the same are disclosed. In a transparent display panel, a VSS voltage line does not surround an outer periphery of a display region. Rather, upper and lower VSS voltage lines respectively disposed on upper and lower sides to the display region are electrically connected to each other via at least one VSS voltage connection line extending across the display region. Thus, left and right non-transparent and thick VSS voltage lines disposed on the left and right sides to the display region may be omitted. Thus, a transparent region of the transparent display panel and a bezel of a transparent display device may be increased or maximized or the bezel thereof may be made slim.

Abstract: A transparent display panel has an auxiliary electrode region including a partition wall whose a width of a top face is larger than that of a bottom face thereof. The auxiliary electrode region is disposed on a line region within a display region. A second electrode of an organic light-emitting element and a VSS voltage connection line is electrically connected to each other via an auxiliary electrode, such that electrical resistance of the second electrode as a transparent electrode is reduced. Further, the auxiliary electrode region is formed on each of a plurality of line regions respectively including VSS voltage connection lines extending across the display region. Thus, a current is fed to each pixel in the display region in a smooth manner, such that luminance distribution across the panel is uniform.
