Abstract

The invention relates to a transparent display device which can improve transmittance and definition. The transparent display device includes: a plurality of first signal lines extending in a first direction and disposed to be spaced apart from each other; a plurality of second signal lines extending in the second direction and disposed to be spaced apart from each other; a transmission region disposed between two adjacent first signal lines and between two adjacent second signal lines; and a pixel including a plurality of sub-pixels disposed based on an intersection region in which the first signal line and the second signal line intersect each other. At least one side in each of the plurality of sub-pixels, which is directed toward the transmission region, has an inclination with respect to each of the first signal line and the second signal line.

Description

technical field [0001] The present disclosure relates to a transparent display device. Background technique [0002] With the development of an information society, demands for display devices that display images have increased in various forms. Recently, various types of display devices, such as liquid crystal display (LCD) devices, plasma display panel (PDP) devices, and organic light emitting display (OLED) devices, quantum dot light emitting display (QLED) devices, have been widely utilized. [0003] Recently, research into a transparent display device for allowing a user to see through the display device an object or an image arranged on an opposite side of the display device is actively being conducted. [0004] The transparent display device includes a display area on which an image is displayed and a non-display area, wherein the display area may include a transmissive area and a non-transmissive area, and the transmissive area may transmit external light. A transp...
