Abstract
The present disclosure provides a current mirror circuit including a first transistor configured to be supplied with a data current from a data driving circuit; a second transistor configured to drive a light emitting diode by mirroring the data current transferred to the first transistor; a capacitor disposed between the first transistor and the second transistor and configured to store a voltage of a gate terminal of the second transistor therein; and a first switch disposed between the first transistor and the second transistor and configured to adjust an input current of the gate terminal of the second transistor.
