Abstract: A display apparatus includes a substrate including a display area and a non-display area, a display element layer, a pad group, a touch electrode layer, and a touch insulation layer. The display element layer includes display elements disposed in the display area. The pad group is disposed on the substrate and includes output pads disposed in the non-display area. The output pads include central output pads and outer output pads disposed outside the central output pads in a first direction. The touch electrode layer is disposed on the display element layer. The touch insulation layer is disposed on the display element layer and contacts the touch electrode layer. A groove pattern is defined in the touch insulation layer overlapping the non-display area, and does not overlap at least a predetermined number of the outer output pads in a second direction.
