Abstract: A pixel circuit connects one terminal of a second capacitor to a line of an anode initialization gate signal rather than an anode of a light emitting element such that a change of a gate-source voltage of a first transistor is prevented. The change of the gate-source voltage of the first transistor is prevented, and thus a change of a driving current generated by the first transistor is prevented. Therefore, any damage due to a deterioration of the light emitting element receiving the driving current is prevented, and a luminance accuracy of the light emitting element is preserved.
