1. A display device comprising:
a display panel with a light emitting area from which a light exits is defined; and
an input sensor disposed on the display panel, the input sensor comprising:
a first conductive layer;
a first insulating layer disposed on the first conductive layer and provided with a diffraction grating defined therein to correspond to the light emitting area; and
a second conductive layer disposed on the first insulating layer and connected to the first conductive layer, the first insulating layer comprising:
an organic layer covering the first conductive layer; and
an inorganic layer disposed on the organic layer, wherein the organic layer and the inorganic layer comprise a plurality of holes defined therein to define the diffraction grating,
wherein the plurality of holes extend entirely through the organic layer and the inorganic layer with respect to a widthwise direction of the first insulating layer.
