Abstract: A display device includes a base substrate including a display area and a non-display area at a periphery of the display area; a first signal wiring on the non-display area of the base substrate and including a first wiring part and a second wiring part connected to the first wiring part; and a printed circuit board including a lead wiring on the first signal wiring. The second wiring part includes an open part passing through a surface of the second wiring part in a thickness direction, the second wiring part includes a long side extending along a first direction and a short side extending along a second direction intersecting the first direction, and a separation distance between the open part and an end of the short side of the second wiring part in the first direction is within about 0.4 times the long side of the second wiring part.
