Abstract
A display device includes: a light emitting element on a substrate; a first transistor configured to control a driving current flowing in the light emitting element; a second transistor configured to supply a data voltage to the gate electrode of the first transistor based on a first gate signal; a third transistor configured to supply a first reference voltage to the gate electrode of the first transistor based on a second gate signal; a fourth transistor configured to supply a second reference voltage different from the first reference voltage to the drain electrode of the first transistor based on a third gate signal; a fifth transistor configured to supply a driving voltage to the drain electrode of the first transistor based on a first emission signal; and a hold capacitor connected between a second reference line supplying the second reference voltage and the source electrode of the first transistor.
