Abstract: A display device includes a display panel including an emission area and a non-emission area proximate to the emission area, and an input sensor disposed on the display panel. The input sensor includes a first sensor conductive layer disposed on the display panel, a first sensor insulation layer disposed on the first sensor conductive layer, and a second sensor conductive layer disposed on the first sensor insulation layer. The first sensor conductive layer and/or the second sensor conductive layer includes sides on which mesh openings overlapping the emission area are defined, wherein recesses are defined in the sides.

Abstract: A display apparatus including a display panel, an input sensor having an active area having a plurality of electrodes disposed therein and at least a portion of which overlaps the display area, and a non-active area which overlaps the non-display area. The active area has a central area and a peripheral area disposed outward from the central area. The plurality of electrodes include center electrodes which are disposed in the central area and peripheral electrodes which are disposed in the peripheral area and have a surface area less than that of the center electrodes. Each of the center electrodes includes a sensing pattern and a floating pattern, and each of the peripheral electrodes includes substantially only the sensing pattern. Thus, an embodiment of the inventive concept may provide the display apparatus that includes an input sensor having improved sensitivity in a peripheral area.
