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: Disclosed are a display panel in which a unit pixel is divided into a wide-angle area and a narrow-angle area in which at least sub-pixel is disposed and light emission is individually and selectively performed, a display device including the same, and a manufacturing method thereof. A semi-cylindrical lens is disposed in the wide-angle area so as to cover a plurality of sub-pixels. Semi-spherical lenses are disposed in the narrow-angle area so as to cover sub-pixels respectively. Therefore, a direction of light emitting from a light-emitting layer is controlled by adjusting a refractive index of each of the lenses in the wide-angle area and the narrow-angle area. Thus, a viewing angle is controlled.

Abstract: A transparent display panel and a transparent display device including the same are disclosed. A transparent display panel includes a substrate having a display region including a plurality of light-emitting regions and a plurality of transmissive regions; and a plurality of line regions disposed over the substrate and extending across the display region, wherein an outer contour of each of the transmissive regions is at least partially curved or wherein each of the transmissive regions has a polygonal shape, and all internal angles of the polygon shape are obtuse. Thus, parallel regularity and periodicity of array of transmissive regions are avoided wherein a haze value is reduced by reducing or minimizing occurrence of light diffraction, and thus, clarity or visibility of an image is improved.

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.
