A display device includes a driving circuit that applies an active potential which is a potential for turning on pixel transistors sequentially to a plurality of output signal lines, wherein the driving circuit includes a main driving circuit that outputs the active potential to one end of the output signal line of the plurality of output signal lines by applying a clock signal caused by a input of the active potential output from the upper output signal line, and an auxiliary driving circuit that has an auxiliary transistor which is a transistor where the other end of the output signal line is connected to a signal line for the clock signal via the source or the drain. Thereby, output waveform distortion in the scanning signal line can be improved and thus display quality can be enhanced.
