1. A display device comprising:
a display panel including a first non-folding region, a second non-folding region, and a folding region disposed between the first non-folding region and the second non-folding region; and
a digitizer including:
a base layer;
first conductive lines disposed on the base layer;
a first cover layer disposed on the first conductive lines;
second conductive lines disposed on the first cover layer;
a second cover layer disposed on the second conductive lines,
wherein a plurality of via-holes passes through the first cover layer,
a second conductive line of the second conductive lines is electrically connected to a first conductive line of the first conductive lines through the plurality of via-holes; and
wherein
the first non-folding region, the folding region, and the second non-folding region are distinguished based on a first direction,
the plurality of via-holes overlaps the folding region, and
a minimum of shortest lengths of gaps along the first direction between all adjacent via-holes immediately next to each other among the plurality of via-holes is equal to or greater than an average diameter of the plurality of via-holes.
