Abstract: A display device includes first and second input sensors and a display panel. The first and second input sensors are disposed in different sensing areas from each other. The first and second input sensors each include a first electrode and a second electrode crossing the first electrode. The first and second trace lines are connected to the first electrode. The trace line of the first and second trace lines, that overlaps the sensing area, overlaps the first electrode and does not overlap the second electrode in the sensing area.

Abstract: A sensor layer includes: first sensing electrodes extending in a first direction; second sensing electrodes extending in a second direction; and first electrodes extending in the first direction. The first sensing electrodes includes first sub electrodes, and the first electrodes includes second sub electrodes. The first sub electrodes includes first patterns, and a first bridge pattern electrically connected to the first patterns. Two first sub electrodes are electrically connected to each other at one end via a first connection line. Two second sub electrodes overlapping with the two first sub electrodes are connected to each other at a second end via a second connection line. The second connection line and another adjacent second connection line are electrically connected to each other via a third connection line. The first connection line is electrically connected to a first pad, and the third connection line is electrically connected to a second pad.

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.
