There is provided a pixel circuit capable of obtaining high-luminance while suppressing power consumption. Further, there are provided a display panel having the pixel circuit, and a display device including the display panel. Still further, there is provided an electronic unit including the display device. The pixel circuit includes a first transistor driving a light-emitting element, a plurality of holding capacitors connected in series between a gate and a source of the first transistor, a second transistor provided between a first signal line and the gate of the first transistor, and a third transistor provided between a second signal line and one of junctions of the holding capacitors.
