Abstract
A display device includes: a plurality of first signal lines, a plurality of second signal lines, and a plurality of sensing pads. The first signal lines are disposed in a first direction, and are parallel to each other. The second signal lines are disposed in a second direction, and are parallel to each other. The second signal lines are substantially perpendicular to the first signal lines. A first row and a second row of the sensing pads are disposed in zigzag in the second direction.
