  • Patent number: 11737324
    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.
