1. A touch device comprising:
a plurality of touch electrodes extending in a first direction, arranged along a second direction intersecting the first direction, and spaced apart from each other, wherein each of the plurality of touch electrodes has a first end and a second end;
a plurality of first traces that is connected to the first ends of a plurality of first touch electrodes among the plurality of touch electrodes, the plurality of first traces being not connected to the second ends of the plurality of first touch electrodes;
a plurality of second traces that is connected to the second ends of a plurality of second touch electrodes among the plurality of touch electrodes, the plurality of second traces being not connected to the first ends of the plurality of second touch electrodes; and
a touch controller configured to correct a plurality of first output signals received through the plurality of first traces, based on a first reference output signal of a first-first touch electrode among the plurality of first output signals and a second reference output signal of a second-first touch electrode among a plurality of second output signals received through the plurality of second traces, wherein the first-first touch electrode is a first touch electrode adjacent to the plurality of second touch electrodes among the plurality of first touch electrodes, and the second-first touch electrode is a second touch electrode adjacent to the plurality of first touch electrodes among electrode among the plurality of second touch electrodes.
