Display apparatus

A display apparatus comprising:

• a substrate comprising a display area and a non-display area disposed outside the display area;
• signal lines disposed on the substrate;
• a display element layer disposed on the signal lines and comprising display elements disposed in the display area;
• a pad group electrically connected to the signal lines and comprising output pads disposed in the non-display area;
• an intermediate insulation layer disposed between the signal lines and the display element layer and exposing the output pads;
• a touch electrode layer disposed on the display element layer;
• a touch insulation layer disposed on the display element layer, contacting the touch electrode layer, and in which a groove pattern is defined in the non-display area;
• and
• a compensation pattern disposed on the touch insulation layer and overlapping the groove pattern,
• wherein the output pads comprise central output pads and outer output pads disposed outside the central output pads in a first direction which is an extension direction of a short side of each of the output pads
• the groove pattern is disposed between the output pads and the intermediate insulation layer, and
• the compensation pattern overlaps at least a predetermined number of the outer output pads in a second direction crossing the first direction in a plan view.

• signal lines disposed on the substrate;
• a display element layer disposed on the signal lines and comprising display elements disposed in the display area;
• a pad group electrically connected to the signal lines and comprising output pads disposed in the non-display area;
• a driving circuit chip which contacts the pad group and provides a signal to the signal lines;
• a touch electrode layer disposed on the display element layer;
• and
• a touch insulation layer disposed on the display element layer and in which a groove pattern is defined in the non-display area,
• wherein the output pads comprise central output pads and outer output pads disposed outside the central output pads in a first direction,
• the groove pattern overlaps the driving circuit chip and does not overlap the pad group, and
• the groove pattern does not overlap at least a predetermined number of the outer output pads in a second direction crossing the first direction in a plan view.
