<p>A display device where low power consumption is realized without lowering aperture ratio is provided. A liquid crystal capacitive element Clc is sandwiched between a pixel electrode 20 and an opposite electrode 80. The pixel electrode 20, one end of a first switch circuit 22, one end of a second switch circuit 23 and a first terminal of a second transistor T2 form an internal node N1. The other terminals of the first switch circuit 22 and the second switch circuit 23 are connected to a source line SL and a voltage supply line VSL, respectively. The second switch circuit 23 is a series circuit including a transistor T1 and diode D1. A control terminal of the transistor T1, a second terminal of the transistor T2 and one end of a boost capacitive element Cbst form an output node N2. The other end of the boost capacitive element Cbst and the control terminal of the transistor T2 are connected to a boost line BST and a reference line REF, respectively. The diode D1 has a rectifying function from the voltage supply line VSL to the internal node N1.</p> |
