Abstract: A display apparatus may include a substrate including a display portion, and a non-display portion at a periphery of the display portion and including a pad area. The display apparatus may further include a plurality of signal lines at the display portion and the non-display portion, a plurality of pads respectively connected with the plurality of signal lines in the pad area, and an insulation layer on the substrate between the plurality of pads. A first distance between the substrate and a center portion of the insulation layer may be smaller than a second distance between the substrate and a periphery portion of the insulation layer.
