A data line driving circuit for a display panel includes a plurality of output circuits, a bias circuit, and a plurality of switches. Each of the plurality of output circuits includes an electric current source which supplies electric current in response to a bias signal, and supplies a data voltage by using the electric current to a corresponding one of a plurality of data lines arranged in the display panel. The bias circuit generates the bias signal, and supplies the bias signal to the plurality of output circuits through bias wirings. The plurality of switches is provided between the bias circuit and the plurality of output circuits, and cuts off the bias wirings in response to a control signal.
