1. A pixel circuit comprising:
a light-emitting element;
a first capacitor, which is a metal insulator metal (MIM) capacitor;
a second capacitor, which is a metal oxide semiconductor (MOS) capacitor;
a sampling transistor configured to supply data voltage from a data line to the first capacitor; and
a driving transistor configured to supply, according to a voltage stored in the first capacitor, driving current from a first voltage line to the light-emitting element.
