Abstract
A display device includes a display panel and an input sensing circuit. The input sensing circuit includes a plurality of sensors and signal lines electrically connected to each of the plurality of sensors. Each of the plurality of signal lines includes a lower line and an upper line overlapping the lower line, and the lower line and the upper line are electrically connected in a plurality of contact areas. A long signal line among the plurality of signal lines has more contact areas than a short signal line.
