ABSTRACT:
A sample hold circuit includes a first switch connected between a data line and a first node, a second switch connected between first node and a second node, a capacitor connected between the second node and a line of a common potential, and a drive circuit applying a potential equal to that of the second node to the first node and one of the electrodes of the liquid crystal cell. The first and second switches are turned on when a scanning line is at an “H” level.
