Claim 18:
19. A display device, comprising:
a display unit comprising a plurality of emission areas which emit light; and
a plurality of touch electrodes disposed on the display unit to detect a touch input,
wherein a first touch electrode includes a first pattern corresponding to first location information, and a second touch electrode includes a second pattern corresponding to second location information,
wherein the touch electrodes are formed in a mesh shape in a plan view and surround at least one of the emission areas,
wherein the touch electrodes comprise:
a reference point, which is used to identify the first and second patterns, wherein the reference point corresponds to an area between intersecting touch electrodes, the area including a first cut between first and second parts of one of the intersecting touch electrodes that protrude towards and face each other and a second cut between third and fourth parts of the other one of the intersecting touch electrodes that protrude towards and face each other, wherein ends of the first and second parts at the first cut are not connected to each other and ends of the third and fourth parts at the second cut are not connected to each other;
a first reference line extending from the reference point along a plurality of intersection points of the touch electrode that are arranged in a first direction; and
a second reference line defined by connecting a plurality of intersection points and a cutout part, the intersection points disposed in a second direction intersecting the first direction from the reference point, the cutout part being disposed between the intersection points,
the first and second patterns are disposed in an area defined by the first and second reference lines, the area including a plurality of rows and a plurality of columns,
the touch electrodes are not physically connected to each other in the reference point, and
the reference point and the cutout part of the second reference line have the same shape.
