Abstract: A display device includes a substrate, a transistor on the substrate, a pixel electrode connected to the transistor, a bank layer disposed on the pixel electrode and defining a pixel opening overlapping the pixel electrode, an emission layer in the pixel opening, a common electrode on the emission layer and the bank layer, an encapsulation layer on the common electrode, a sensing electrode on the encapsulation layer, a first insulating layer disposed on the encapsulation layer and overlapping the pixel opening, a second insulating layer on the first insulating layer, and a third insulating layer surrounding the first insulating layer. A refractive index of the first insulating layer, a refractive index of the second insulating layer, and a refractive index of the third insulating layer are different from one another, and the refractive index of the first insulating layer is greater than the refractive index of the third insulating layer.
