Abstract: A display apparatus may include a substrate, a display element disposed above the substrate, an encapsulation layer disposed above the display element and including an inorganic encapsulation layer and an organic encapsulation layer, and a touch-sensing layer disposed above the encapsulation layer. The touch-sensing layer may include a first insulating layer including a side surface inclined with respect to a top surface of the encapsulation layer and including an organic material. The touch-sensing layer may include a conductive layer including sensing electrodes, and a second insulating layer covering the conductive layer and including a refractive index that may be different from that of the first insulating layer.
