1. A display device, comprising:
a display panel that comprises a display area and a pad terminal area disposed adjacent to the display area; and
a first circuit board that is attached to the pad terminal area of the display panel, wherein
the first circuit board comprises a first film that has at least one first lead terminal row in which one or more first lead terminals are arranged along the first direction and a second film that has at least one second lead terminal row in which one or more second lead terminals are arranged along the first direction,
the pad terminal area comprises a first pad terminal area that has at least one first pad terminal row in which one or more first pad terminals are arranged along a first direction and a second pad terminal area that has at least one second pad terminal row in which one or more second pad terminals are arranged along the first direction, wherein
the first pad terminal row comprises a first sub-pad terminal row and a second sub-pad terminal row which are spaced apart from each other in a second direction intersecting the first direction,
the second pad terminal row comprises a third sub-pad terminal row and a fourth sub-pad terminal row which are spaced apart from each other in the second direction,
the first lead terminals are connected to the first pad terminals,
the second lead terminals are connected to the second pad terminals,
a first end of the second film protrudes from a first end of the first film toward the display area, and
the second pad terminal area overlaps an area between the first end of the first film and the first end of the second film,
the first pad terminals of the first sub-pad terminal row and the second sub-pad terminal row are staggered, wherein a first pad terminal of one sub-pad terminal row overlaps two closest first pad terminals of an adjacent sub-pad terminal row, and
the second pad terminals of the third sub-pad terminal row and the fourth sub-pad terminal row are staggered, wherein a second pad terminal of one sub-pad terminal row overlaps two closest second pad terminals of an adjacent sub-pad terminal row,
the first circuit board further comprises an insulating layer disposed between the first film and the second film, and contact holes that penetrate through the first film and the insulating layer, and
the contact holes overlap the driver integrated circuit.
