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.

Abstract: A display device having a mirror function includes a first substrate, a light emitting portion, a second substrate, a mirror portion, and a cover layer. The light emitting portion is on a surface of the first substrate. The mirror portion is on a surface of the second substrate facing the first substrate and has an opening overlapping the light emitting portion. The cover layer is on a surface of the second substrate and covers a portion of the opening.

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.
