Abstract
A display panel includes a display panel and an input sensor disposed on the display panel. The input sensor includes an active region and an inactive region at least partially surrounding the active region. The input sensor includes a plurality of sensing electrodes disposed in the active region, a plurality of sensing lines disposed in the inactive region and connected to the sensing electrodes, a ground line extending outwardly to a greater extent than the sensing lines in the inactive region, and at least one shield layer extending from the ground line in the inactive region.
