[Solution] In the present invention, a signal output circuit alternatingly provides a reference voltage and an image signal voltage to a data line, and has the following: an output node to which the data line is connected; a reference voltage node to which a reference voltage is imparted; a source amplifier that outputs the image signal voltage in accordance with an input gradation signal; a first switch that is disposed between the output side of the source amplifier and the output node; a second switch disposed between the reference voltage node and the output node; and a third switch provided to the power supply path of the source amplifier. Within a scanning period for scanning a display element in row units, switching is performed between a state in which a first switch is non-conductive and a second switch is conductive, and a state in which the first switch is conductive and the second switch is non-conductive. The third switch is put in a conductive state if the first switch is caused to be in a conductive state, and is put in a non-conductive state if the first switch is caused to be in a non-conductive state. |
