Abstract
Provided is a pixel circuit capable of preventing slight light emission of an organic EL element due to leakage current from a driving transistor. Provided is a pixel circuit including: a light-emitting element that emits light at luminance corresponding to an amount of current; a first capacitance, which is a metal insulator metal (MIM) capacitance; and a second capacitance, which is a metal insulator semiconductor (MIS) capacitance disposed in parallel to the light-emitting element.
