Abstract: A pixel circuit includes first to fifth transistors, a capacitor, and a light emitting element. The first transistor is coupled between first and second power lines, and includes a gate electrode coupled to a first node and a back-gate electrode coupled to a second node. The second transistor is coupled between a data line and the first node, and includes a gate electrode coupled to a first scan line. The third transistor is coupled between a third power line and the first node, and includes a gate electrode coupled to a reference scan line. The fourth transistor is coupled between a second node and a fourth power line, and includes a gate electrode coupled to a second scan line. The fifth transistor is coupled between a first power line and the one electrode of the first transistor, and includes a gate electrode coupled to a light-emitting control line.
