Abstract: A display device including a base member, a plurality of transistors, a plurality of pad parts, a plurality of signal lines, and a blocking pad. Each of the plurality of transistors includes a control electrode, an input electrode, and an output electrode, and is disposed on the center area. The blocking pad is disposed between two adjacent signal lines among the plurality of signal lines. A part of the blocking pad is disposed on the same layer as at least any one of the control electrode, the input electrode, and the output electrode.
