A display device includes the following elements: a base substrate having an active area and a non-active area; a plurality of pads disposed on the non-active area; and a printed circuit disposed on the plurality of pads. The printed circuit may include the following elements: a support layer; a first conductive layer and a second conductive layer respectively disposed on two opposite surfaces of the support layer. The second conductive layer may include the following elements: a first conductive member; a second conductive member; and a space between the first conductive member and the second conductive member. The first conductive member and the second conductive member may be electrically connected to the first conductive layer through contact holes. A side surface of the base substrate may be positioned between two edges of the space in a direction parallel to the support layer.
