Abstract: A pixel includes a first transistor generating current from a first power source line to a second power source line through a light-emitting element, a second transistor between a third power source line and a gate electrode of the first transistor, a third transistor between a data line and a gate electrode of the second transistor and controlled by a first signal, a fourth transistor between a fourth power source line and a first node and controlled by a second signal, a first capacitor between the gate electrode of the first transistor and the first node, and a second capacitor between the gate electrode of the second transistor and a sweep voltage line providing a sweep voltage that linearly changes from a first voltage level to a second voltage level, and nonlinearly changes from the second voltage level to a third voltage level when the third transistor is on.

Abstract: A display device includes: a plurality of pixels connected to scan lines, emission control lines, data lines, and a power line; a scan driver configured to supply a scan signal to the scan lines; and an emission driver configured to supply an emission control signal to the emission control lines, wherein a voltage of a first power supplied to the power line during an inspection period has a pulse form alternating between a first level and a second level that is lower than the first level, and the display device is configured to maintain the voltage of the first power at a third level.
