Display device and driving method of the same

A first capacitor obtained according to the first transistor gate-source voltage of the programming current flowing through the first transistor, the threshold voltage of the second capacitor to obtain the second transistor. Then, the charge held in the first and second capacitors are capacitively coupled. By using capacitive coupling voltage obtained as the gate-source voltage of the first transistor to the light emitting element may be provided according to a constant current programming current.
