1. A display device comprising:
a first substrate including a display area and a non-display area, which is on a periphery of the display area;
a light-emitting element disposed on the first substrate and in the display area;
a display signal line which is disposed on the first substrate and in the display area, extends in a first direction, and transmits a signal to the light-emitting element;
a common voltage supply line disposed on the first substrate and in the non-display area;
a display pad disposed on the first substrate and in the non-display area, and electrically connected to the display signal line;
a dummy pad disposed on the first substrate and in the non-display area, and electrically connected to the common voltage supply line; and
a circuit board coupled to the first substrate,
wherein the dummy pad is disposed closer than the display pad to edges of the first substrate in a second direction, which intersects the first direction,
wherein the circuit board includes a terminal line,
a display terminal which is electrically connected to the terminal line and is electrically connected to the display pad, and
a dummy terminal which is not electrically connected to the terminal line or to any other pad or circuits on the circuit board and is electrically connected to the dummy pad on the first substrate.
