1. A display device comprising:
a pixel defining layer on a substrate and having a first opening defining a light emission area;
a light emitting element layer in the light emission area and comprising an anode electrode;
a sensing electrode on the pixel defining layer and having a second opening overlapping the first opening; and
a first organic layer covering the sensing electrode and having a third opening overlapping the first opening,
wherein a width of the second opening is greater than a width of the first opening in a plan view,
wherein a width of the third opening is greater than the width of the first opening and is smaller than the width of the second opening in the plan view, and
wherein a width of the anode electrode is greater than the width of the first opening and is smaller than the width of the third opening in the plan view.
