1. A display device comprising:
a substrate;
a pixel electrode disposed on the substrate;
a bank layer in which a pixel opening is defined, the bank layer being disposed on the pixel electrode;
an encapsulation layer disposed on the pixel electrode and the bank layer;
a sensing electrode disposed on the encapsulation layer;
a first insulating layer which is disposed on the sensing electrode and in which an opening overlapping the pixel opening is defined; and
a second insulating layer disposed on the first insulating layer and having a higher refractive index than a refractive index of the first insulating layer,
wherein the opening of the first insulating layer includes a first edge and a second edge separated from an edge of the pixel opening and extending in different directions from each other in a plan view, and a first extension part disposed at a portion where the first edge and the second edge meet in the plan view, and
the first extension part protrudes from the portion where the first edge and the second edge meet in the plan view.
