Abstract
A method of manufacturing a display apparatus includes providing a substrate, forming a display unit defining an opening portion in a display region over the substrate, forming a thin film encapsulation layer to seal the display unit, forming a touch electrode over the thin film encapsulation layer, forming a touch insulating film covering the touch electrode such that the thin film encapsulation layer and the touch insulating film are sequentially stacked and formed over the substrate in the opening portion, forming a touch contact hole by removing a portion of the touch insulating film to expose a portion of the touch electrode, and removing a portion of the touch insulating film and a portion of the thin film encapsulation layer formed in the opening portion to expose a portion of the substrate during the forming of the touch contact hole.
