In a display device, a liquid crystal capacitive element is sandwiched between a pixel electrode and an opposite electrode. The pixel electrode, one end of a first switch circuit, one end of a second switch circuit and a first terminal of a second transistor form an internal node. The other terminals of the first switch circuit and the second switch circuit are connected to a source line. The second switch circuit is a series circuit composed of a first transistor and a diode. A control terminal of the first transistor, a second terminal of the second transistor and one end of a boost capacitive element form an output node. The other end of the boost capacitive element and the control terminal of the second transistor are connected to a boost line and a reference line, respectively.
