1. A display device comprising:
a display panel comprising a display area and a panel pad area around the display area, the panel pad area comprising a plurality of panel signal lines; and
a first circuit board having a first end attached to the panel pad area and a second end opposite the first end,
the first circuit board comprising:
a first line layer comprising a plurality of first lead lines;
an insulating layer on the first line layer;
a second line layer on the insulating layer and comprising a plurality of second lead lines; and
a driving integrated circuit on the second line layer,

wherein the plurality of second lead lines comprises:
a first sub-lead line configured to supply a first-high voltage signal from the driving integrated circuit to the plurality of panel signal lines;
a second sub-lead line configured to supply a first-low voltage signal from the driving integrated circuit to the plurality of panel signal lines;
a third sub-lead line physically connected to the driving integrated circuit;
a fourth sub-lead line separated from the third sub-lead line in a first direction;
a fifth sub-lead line spaced apart from the third sub-lead line in a second direction intersecting the first direction; and
a sixth sub-lead line spaced from the fourth sub-lead line in the second direction, wherein the fifth sub-lead line and the sixth sub-lead line and are electrically connected to a second circuit board, and

wherein the second direction is toward the second circuit board from the plurality of first lead lines.
