Abstract
A display device includes a display panel with a light emitting area from which a light exits and an input sensor disposed on the display panel. The input sensor includes 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 includes an organic layer covering the first conductive layer and an inorganic layer disposed on the organic layer. The organic layer and the inorganic layer include a plurality of holes defined therein to define the diffraction grating.
