Abstract

A transparent display device is disclosed, which may improve yield and reduce a tact time, and may reduce resistance of a power line. 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 surrounding the display area, first and second pads provided over the substrate, a first pixel power line extended between a pad area in which the first pad and the second pad are disposed and the display area in a first direction, a first common power line extended between the first pixel power line and the display area in the first direction, a first common power connection electrode electrically connecting the second pad with the first common power line, and a second common power connection electrode disposed in a layer different from the first common power connection electrode, electrically connecting the second pad with the first common power line.

Description

technical field [0001] The present disclosure relates to a transparent display device. Background technique [0002] With the development of the 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, 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 enabling a user to view an object or an image arranged on the opposite side of the display device after seeing through the display device is actively being conducted. [0004] In the related art, when a transparent display device is manufactured, after an anode electrode is formed, a process of testing a defect of a driving transistor is performed. If a defect occurs in the driving transistor, a repair process is perfor...
