To effectively suppress the degradation of display quality, which is caused by errors included in a current supplied to an electro-optical element.
A pixel circuit includes a capacitor C1, transistors T1 and T2 constituting a current mirror, and an organic EL element OLED. When a first driving mode is set, the transistor T1 functions as a programming element for writing data corresponding to a data current Idata to the capacitor C1, and the transistor T2 functions as a driving element for generating a driving current Ioled in accordance with data held in the capacitor C1. When a second driving mode periodically switched to the first driving mode alternately is set, the transistor T1 functions as a programming element, and the transistor T1 functions as a driving element.
