<p>A display device which realizes a multi-gradation constant display with low power consumption is provided. A pixel circuit 2 includes an internal node N1 holding a pixel data voltage applied to a display element part 21, a first switch circuit 22 transferring the pixel data voltage supplied from a data signal line SL to the internal node N1 through a series circuit of first and second transistor elements T1 and T2, a second switch circuit 23 including a third transistor element T3 connecting a middle node N2, at which the first and second transistor elements T1 and T2 are connected, with a voltage supply line VSL, and a control circuit 24 including a series circuit of a fourth transistor element T4 and a first capacitive element C1, holding the pixel data voltage held in the internal node N1 at one end of the first capacitive element C1 through the fourth transistor element T4, and controlling on/off of the third transistor element T3 by a boost voltage applied to the other end of the first capacitive element C1.</p> |
