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.
