High resolution display device

A display device comprising:

• a substrate including a plurality of first pad terminals and a plurality of second pad terminals;
• and
• a printed circuit board including a base film, a plurality of third pad terminals and a plurality of fourth pad terminals,
• wherein the substrate further comprises:
• each of the plurality of first pad terminals includes a first column sub-pad terminal, and a second column sub-pad terminal;
• and
• each of the plurality of second pad terminals includes a pair of second sub-pad terminals,
• wherein the printed circuit board further comprises:
• each of the plurality of third pad terminals includes a third column sub-pad terminal, and a fourth column sub-pad terminal;
• each of the plurality of fourth pad terminals includes a pair of fourth sub-pad terminals;
• a first terminal wiring connected to the third column sub-pad terminal through a first contact hole formed in the base film;
• and
• a second terminal wiring connected to one of the pair of fourth sub-pad terminals through a second contact hole formed in the based film,
• wherein:
• the first column sub-pad terminal is electrically connected to the third column sub-pad terminal,
• the second column sub-pad terminal is electrically connected to the fourth column sub-pad terminal,
• one pad terminal of the pair of second sub-pad terminals is electrically connected to one pad terminal of the pair of fourth sub-pad terminals, and
• another pad terminal of the pair of second sub-pad terminals is electrically connected to another pad terminal of the pair of fourth sub-pad terminals, and
• wherein:
• the first contact hole overlaps the third column sub-pad terminal in a plan view, and
• the second contact hole is disposed to be separated in the plan view.
