Claim 7:
8. The display apparatus of claim 7, wherein the constant current generator circuit is configured to, in each of the plurality of light emitting sections, provide the constant current to the corresponding inorganic light emitting element while a driving voltage is applied to a source terminal of the first driving transistor,
wherein the PWM circuit is configured to, in each of the plurality of light emitting sections, apply the driving voltage to the source terminal of the first driving transistor during a time period in which the second driving transistor is turned on while a voltage of a gate terminal of the second driving transistor changes according to a change of the sweep voltage, and
wherein the time period in which the second driving transistor is turned on changes based on a magnitude of the PWM data voltage.
