Abstract: A display device includes a display panel and an input sensor disposed on the display panel. The input sensor includes a plurality of first areas repeatedly arranged in a first direction, a plurality of second areas repeatedly arranged in the first direction, an inorganic insulating layer disposed in the first areas, an organic insulating layer disposed in the first areas and the second areas, and a sensing electrode disposed on the organic insulating layer. The first areas are alternately arranged in the first direction with the second areas, and the input sensor includes openings in the second areas that are formed by removing portions of the inorganic insulating layer from the second areas.
