Original Abstract Submitted
A display device includes a substrate including a display area including pixels and a non-display area around the display area and including a pad area, and a circuit board attached to the pad area. Pad electrodes arranged along a first direction and a first alignment mark located at a side of the pad electrodes in the first direction and protruding more than the pad electrodes are disposed on the substrate in the pad area. The circuit board includes a base portion, and lead electrodes disposed on the base portion and respectively facing the pad electrodes. A first alignment mark hole is defined through the base portion at a side of the lead electrodes in the first direction, the first alignment mark and the first alignment mark hole have a same shape as each other, and the first alignment mark is accommodated in the first alignment mark hole.
