Abstract
A pixel circuit of a display device includes an electro-optical element, a drive transistor, a first transistor including a first conduction terminal connected to an anode terminal of the electro-optical element, a second conduction terminal to which an initialization voltage is applied, and a gate terminal connected to a scanning line, a second transistor including a first conduction terminal connected to a gate terminal of the drive transistor and a gate terminal connected to an immediately preceding scanning line selected in a horizontal interval immediately before the scanning line is selected, and a third transistor being diode-connected and including a drain terminal and a gate terminal to which an initialization voltage is applied and a source terminal connected to a second conduction terminal of the second transistor. Thus, a display device that can suppress both the bright spots and the black floating is provided.
