Claim 9:
10. The display apparatus of claim 2, wherein the constant current generator circuit comprises:
a first capacitor connected between a source terminal of the first driving transistor and a gate terminal; and
a third transistor for applying the constant current generator data voltage to the gate terminal of the first driving transistor while being turned on,
wherein the PWM circuit comprises:
a second capacitor including one end to which a linearly changing sweep voltage is applied and the other end connected to a gate terminal of the second driving transistor; and
a fourth transistor configured to apply the PWM data voltage to a gate terminal of the second driving transistor while being turned on,
wherein the drain terminal of the second driving transistor is connected to the gate terminal of the first driving transistor.
