Abstract: A display device is disclosed that includes a pixel layer, a touch sensing layer, and a sensing pattern. The pixel layer includes first pixel units, each including first sub-light emitting regions, and second pixel units, each including second sub-light emitting regions. The touch sensing layer includes sensing electrodes, and driving electrodes electrically insulated from the sensing electrodes, at least some of the sensing electrodes and the driving electrodes each includes a dummy pattern defining dummy openings overlapping the first sub-light emitting regions when viewed in a plan view, and a sensing pattern electrically insulated from the dummy pattern and spaced apart from the first sub-light emitting regions and the second sub-light emitting regions when viewed in a plan view. The light blocking pattern is disposed on the touch sensing layer, defining light blocking openings overlapping the first sub-light emitting regions when viewed in a plan view, and overlapping the first pixel units when viewed in a plan view.

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.
