Abstract:
The present exemplary embodiments provide a touch display device which connects a touch driving circuit and a plurality of touch sensors using a plurality of dummy pixels disposed on a display panel to recognize touch event of a user. When the touch wiring line is implemented, the same material as the pixel electrode or the source line included in the plurality of dummy pixels is used so that a separate process for implementing the touch wiring line is not necessary. Further, in a pixel structure in which one data line is disposed for every two pixels, the source line is disposed in a region where the data line is not disposed to be used as a touch wiring line. Therefore, the touch recognizable area may expand as compared with a case using a pixel metal.
