10. A display device, comprising:
a display panel including a plurality of panel pads arranged along a first direction and a second direction crossing the first direction; and
a driving chip including:
a plurality of output pads respectively electrically connected to the plurality of panel pads of the display panel, wherein the plurality of output pads outputs a data voltage to the plurality of panel pads of the display panel; and
a plurality of dummy pads positioned in the first direction from the plurality of output pads and arranged along the first direction and the second direction,
wherein a plurality of adjacent dummy pads adjacent to the plurality of output pads in the first direction, among the plurality of dummy pads, output a variable voltage,
wherein the plurality of output pads includes an adjacent output pad adjacent to an adjacent dummy pad of the plurality of adjacent dummy pads in the first direction, and
wherein the adjacent dummy pad outputs a voltage the same as the data voltage corresponding to a white grayscale when the adjacent output pad outputs the data voltage corresponding to a black grayscale.
