1. A display device comprising:
a pixel electrode disposed on a substrate;
a pixel defining layer disposed on the pixel electrode and including a pixel opening overlapping the pixel electrode;
an encapsulation layer disposed on the pixel defining layer;
a sensing electrode portion disposed on the encapsulation layer;
a sensing insulating layer overlapping at least part of the sensing electrode portion; and
an adhesive layer disposed on the sensing insulating layer, wherein
the sensing insulating layer includes:
a first region overlapping the sensing electrode portion, and
a second region overlapping the pixel opening,
a portion of the adhesive layer spaces the first region apart from the second region, and
a refractive index of the adhesive layer is less than a refractive index of the sensing insulating layer.
