Abstract

A display device includes: a substrate; a transistor disposed on the substrate; a pixel electrode connected to the transistor; a bank layer disposed on the pixel electrode having a pixel opening overlapping the pixel electrode; an emission layer disposed in the pixel opening; a common electrode disposed on the emission layer and the bank layer; an encapsulation layer disposed on the common electrode; a sensing electrode disposed on the encapsulation layer; a first insulator disposed on the encapsulation layer to overlap the pixel opening; a second insulator disposed outside the first insulator; and a third insulator disposed outside the second insulator. The first insulator has a first refractive index, the second insulator has a second refractive index, and the third insulator has a third refractive index, and the first refractive index, and wherein the second refractive index, and the third refractive index are different from each other.
