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