Abstract
A source line driver includes a first transistor, which has one end connected to one end of a second transistor. The first transistor has the other end connected to power supply. A third transistor has one end connected to the other end of the second transistor. The third transistor has the other end grounded. The second transistor has a control terminal connected to an output terminal of an opamp. The opamp has one input terminal supplied with a reference potential and the other input terminal connected to a node between the first transistor and the second transistor. The node is connected to a source line.
