Display device
A display device may include a display panel, an input sensing unit, and an alignment structure. The display panel may include a sealing member. The input sensing unit may be disposed on the display panel. The input sensing unit may include first-type sensor electrodes directly contacting a face of a first insulator of the display device, a first-type connector electrically connecting the first-type sensor electrodes, second-type sensor electrodes directly contacting the face of the first insulator of the display device, and a second-type connector electrically connecting the second-type sensor electrodes. The alignment structure may overlap the sealing member and may include a transparent member that directly contacts the face of the first insulator of the display device.
