Classification: CPC H  G | IPC G  H

Claim 0:
1. A display device comprising:
a substrate;
a transistor disposed 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 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 insulating layer disposed on the encapsulation layer and overlapping the pixel opening;
a second insulating layer disposed on the first insulating layer; and
a third insulating layer surrounding the first insulating layer,
wherein 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,
the refractive index of the first insulating layer is greater than the refractive index of the third insulating layer, and
a maximum thickness of the third insulating layer is greater than a maximum thickness of the first insulating layer in a direction perpendicular to a main plane extension direction of the substrate so that a maximum height of the third insulating layer from the substrate is greater than a maximum height of the first insulating layer from the substrate.
