Abstract: A touch-sensitive display includes a plurality of electrodes configured to detect a touch input received at the touch-sensitive display device. A plurality of touch wires formed on a substrate are electrically connected to the electrodes and configured to detect a touch input received at the touch-sensitive display device. A plurality of first conductive patterns on the substrate are each connected to a touch wire and extend in a first direction from the corresponding touch wire. An insulation layer is disposed on the plurality of touch wires and first conductive patterns, and a plurality of second conductive patterns are disposed on the insulation layer. Each second conductive pattern contacts one of the touch wires via a contact hole in the insulation layer and at least partially overlaps a corresponding one of the first conductive patterns, while being separated from the corresponding one of the first conductive patterns by the insulation layer.

Abstract: Provided is a touch display device having a hole provided in an active area. Touch electrodes are disposed in at least a portion of the active area, in which the hole is provided and no images are displayed. The touch electrodes disposed in surrounding areas of the hole are easily connected. In a case in which a plurality of holes are disposed in the active area, a structure disposed in the area between the holes to increase the number of the touch electrode connecting lines is provided. This structure increases capacitance-generating areas between the intersecting touch electrode lines, thereby improving the performance of touch sensing in the area between the holes.
