To provide a display of high display grade and low electric power consumption. A source output circuit 24 is provided with an analog switching circuit 26 for switching a source wiring Sj to a reference voltage wiring LN or not. A gate output circuit 12 changes the voltage of a gate wiring Gi according to a prescribed rule during the time of one line time which is the selection period of the gate wiring Gi, and an analog switch circuit 26 changes from an on state to an off state at the timing complying with image data Dj. The voltage of the source wiring Sj coincides with a voltage V0 in a switch on state, changes by accompanying the change in the voltage of the gate wiring Gi after the switch off and attains the level complying with the image data Dj of at the termination of the one line time.; The voltage complying with the image data Dj is applied to the source wiring Sj by using the single voltage VO in the manner described above and thereby a gradation display is performed.
