Abstract

A transparent display device is disclosed, which may have high light transmittance in a non-display area as well as a display area, and may increase or maximize a light emission area in a non-transmissive area. The transparent display device comprises a substrate provided with a display area, in which a plurality of subpixels are disposed, and a non-display area adjacent to the display area, anode electrodes provided in each of the plurality of subpixels over the substrate, a light emitting layer provided over the anode electrodes, a cathode electrode provided over the light emitting layer, a pixel power line provided over the substrate and extended in the display area in a first direction, and a common power line provided over the substrate and extended in the display area in the first direction. The display area includes a non-transmissive area provided with the common power line and the pixel power line, and a transmissive area provided between the common power line and the pixel power 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 used. [0003] Recently, research on a transparent display device for allowing a user to view objects or images arranged on opposite sides of the display device after seeing through the display device is actively being conducted. [0004] The transparent display device may include a display area on which an image is displayed and a non-display area, wherein the display area may include a transmission area and a non-transmission area that may transmit external light. The transparent display dev...
