Abstract:
A reference voltage line is synchronously scanned with scanning of a scanning signal line, voltage of the reference voltage line is set to be the voltage of a common electrode, the second transistor is set to be OFF state during the reference voltage line is set in the common voltage for a pixel wherein a node between an image signal memory and said second transistor is set in a voltage so that said second transistor becomes OFF and the voltage of image signal line is set to be high voltage level when the voltage of the scanning signal line changes from low voltage level to high voltage level for the pixel wherein the node between the image signal memory and the second transistor is set in a voltage so that said second transistor becomes ON.
