Abstract
A transparent display device with a touch sensor can include a plurality of subpixels disposed in a non-transmission area of a substrate, the plurality of subpixels including a light emitting element with an anode electrode, a light emitting layer, and a cathode electrode; and a touch sensor in a transmission area of the substrate and including a touch sensor electrode. Also, the transparent display device can include an undercut structure for separating the cathode electrode from the touch sensor electrode of the touch sensor, in which the undercut structure is in the transmission area of the substrate and includes a plurality of inorganic layers including an opening area between an edge area of the touch sensor and an edge area of one of the plurality of subpixels; and an organic pattern on an edge area of the plurality of inorganic layers, the organic pattern being spaced apart from the subpixels.
