A display device includes: a display panel including a pixel array, a side terminal including a side surface which is exposed to outside the display panel, and a transfer wiring electrically connecting the side terminal and the pixel array to each other; and a side pad which is conductive and through which an electrical signal is provided to the side terminal from outside the display panel, the side pad contacting the display panel at the side surface of the side terminal which is exposed to outside the display panel. An end of the transfer wiring is spaced apart from the side surface of the side terminal which is exposed to outside the display panel.
