1. A display device, comprising:
a display panel; and
an input sensor disposed on the display panel, the input sensor including an active region and an inactive region at least partially surrounding the active region,
wherein the input sensor includes:
a plurality of sensing electrodes disposed within the active region;
a plurality of sensing lines disposed within the inactive region and connected to the plurality of sensing electrodes;
a ground line extending outwardly to a greater extent than the plurality of sensing lines in the inactive region, the ground line surrounding the sensing lines, within the inactive region, on at least three sides thereof in a plan view, and not overlapping the sensing lines in the plan view; and
at least one shield layer extending from the ground line in the inactive region,
wherein a horizontal edge of the at least one shield layer forms a line with a horizontal edge of the active region, in the plan view,
wherein a cathode electrode of the light-emitting element of the pixel has a shape of a distorted rectangle in which two lateral sides thereof are bowed outwardly causing four corners of the cathode electrode to have a bowed angle shape and the cathode electrode overlaps the active region except for corners thereof where the horizontal edge of the active region meets a vertical edge of the active region, in the plan view, the bowed angle shaped of the four corners of the cathode electrode leaving the corners of the active region exposed,
wherein the at least one shield layer covers the corners of the active region that are not exposed by the four corners of the cathode electrode of the light-emitting element of the pixel that have the bowed angle shape, and
wherein the at least one shield layer includes a plurality of shield layers, and the plurality of shield layers are spaced apart from each other and are respectively adjacent to four corners of the active region.
