Abstract: A pixel includes: a light emitting element; a first transistor generating a driving current flowing from a first power line to a second power line; a second transistor being turned on in response to a fourth scan signal; a third transistor being turned on in response to a second scan signal; a fourth transistor being turned on in response to a first scan signal; a fifth transistor being turned on in response to a third scan signal; a sixth transistor being turned off in response to a first emission control signal; a first capacitor; and a second capacitor. A period in which the second transistor is turned on and a period in which the third transistor is turned on do not overlap with each other.
