Abstract
A display unit of the disclosure includes a unit pixel and a driving section that drives the unit pixel. The unit pixel includes a light-emitting device, a capacitor section having a first capacitor and a second capacitor that are coupled in series through a first node, a drive transistor that supplies a drive current corresponding to a potential difference across both ends of the capacitor section to the light-emitting device, and a first transistor that delivers a first voltage to the first node by turning on.
