Claim 0:
1. A pixel circuit comprising:
a driving element including:
a first electrode electrically connected to a first node;
a first gate electrode electrically connected to a second node;
a second electrode electrically connected to a third node; and
a second gate electrode to which an initialization voltage is applied;

a light emitting element including:
an anode electrode electrically connected to a fourth node; and
a cathode electrode to which a power supply voltage is applied, the light emitting element, in operation, being driven according to a current from the driving element;

a first switch element electrically connected between the first node and the second node;
a second switch element electrically connected in series between the third node and the fourth node configured to selectively electrically connect and disconnect the third node to the fourth node;
a first capacitor electrically connected to the first gate electrode of the driving element and to which a data voltage of pixel data is applied; and
a second capacitor electrically connected to the third node and to which the initialization voltage is applied.
