Abstract
A display device is provided, including a first substrate, a plurality of first contact pads, a second substrate, a plurality of second contact pads, and a plurality of first traces. The first substrate includes a display area and a non-display area. The first contact pads disposed on the non-display area. The second substrate includes a first side and a second side, wherein the first side is opposite to the second side. The second contact pads are disposed on the first side, wherein the second contact pads are electrically connected to the first contact pads. The first traces are disposed on the second side, wherein the first traces are electrically connected to the second contact pads through a plurality of through holes respectively, and one of the through holes overlaps corresponding one of the second contact pads in a normal direction of the second substrate.
