Abstract
A pixel capable of adjusting a threshold voltage of a driving transistor, the pixel including: a display element configured to emit light during an emission period and including an anode and a cathode, the first transistor including an upper gate and a lower gate and configured to control a magnitude of a driving current flowing to the display element, a storage capacitor connected to the upper gate of the first transistor, and a second transistor configured to be turned on during a data writing period to transmit a data voltage to the first transistor, wherein a lower gate-source voltage of the first transistor has a first voltage level in the data writing period and a second voltage level in the emission period.
