Abstract
A display unit of the present disclosure includes a plurality of pixel circuits each including a light-emitting element, a drive transistor that has a drain and a source and supplies a current to the light-emitting element, and a control transistor connected to the drain or the source of the drive transistor. One channel portion is formed for two control transistors in respective adjacent two of the pixel circuits.
