Abstract: In a transparent display panel, a GIP region acts as a transmissive region, thereby increasing or maximizing a transmissive area in the GIP region. To this end, a line for VSS voltage application is disposed in a display region. Thus, a non-transparent thick line for applying the VSS voltage is not disposed in an upper portion of a GIP circuit region. Thus, a transparent bezel in which the GIP region acts as the transmissive region is implemented. Further, a GIP input signal line region and a GIP output signal line region constitute different layers, thereby to maximize a spacing between GIP input signal lines, resulting in increasing or maximizing a transmissive area in the GIP circuit region.

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: In a transparent display panel, a layer of each of a VSS voltage connection line and a VDD voltage connection line as a power line in a display region is different from a layer of a data line and a reference voltage connection line, while each of the VSS voltage connection line and the VDD voltage connection line partially overlaps the data line and the reference voltage connection line. Thus, an overall width of a line region may be reduced. Thus, an area of a pixel circuit region is reduced, such that an area of a transmissive region increases, thereby to increase an overall transmittance of the panel. Further, a width of each of the VSS voltage connection line and the VDD voltage connection line is large while reducing or minimizing an area of the line region in the display region. This reduces or minimizes occurrence of VDD drop or VSS rise, thereby to reduce luminance non-uniformity of the panel.
