A circuit for compensating for the threshold voltage nonuniformity and variations includes a transistor having a threshold voltage, a first switching element for switching between the gate and drain electrodes of the transistor, a first capacitor of which first electrode is connected to the contact between the gate electrode of the transistor and the first switching element so as to recognize and store the threshold voltage of the transistor, a second switching element for switching between the second electrode of the first capacitor and the source electrode of the transistor, and a third switching element for switching the input voltage to the second electrode of the first capacitor.
