Abstract
Disclosed is an organic light emitting display device with a touch sensor. The display device has a touch sensor that is directly disposed on a sealing part, thus removing the necessity of an additional adhesion process, simplifying a manufacturing process and reducing manufacture cost. In addition, the display device with the touch sensor includes a display cover electrode of a display pad that is made of a same material as a conductive layer included in the touch sensor, thus preventing damage to the display pad electrode.
Claims26
A display device comprising:
- a thin film transistor disposed in an active region of a substrate that displays images;
- a display pad disposed in a non-active region of the substrate that does not display images;
- a light emitting device connected to the thin film transistor;
- an encapsulation layer on the light emitting device;
- a touch sensor on the encapsulation layer in the active region of the substrate, the touch sensor including a conductive layer;
- a touch pad in the non-active region of the substrate and the touch pad connected to the touch sensor, and
- a routing line that electrically connects the touch sensor and the touch pad, the routing line disposed along upper and side surfaces of the encapsulation layer,
- wherein the display pad includes a display pad electrode and a display cover electrode over the display pad electrode, the display pad electrode connected to at least one of a scan line, a data line, or a voltage power line in the active region and the display cover electrode covering a portion of the display pad electrode and made of a same material as the conductive layer.
