A light emitting display driven by a data current. A first voltage
corresponding to the data current is applied to a first capacitor formed
between a gate and a source of a driving transistor. A second voltage
corresponding to a threshold voltage of the driving transistor is applied
to a second capacitor formed between the gate and source thereof. The
first and second capacitors are coupled to establish the voltage between
the gate and source thereof as a third voltage, and a driving current
from the driving transistor is transmitted to a light emitting element.
In this instance, the driving current is determined by the third voltage.
