Abstract
A display device includes: a display unit including a plurality of first scan lines, a plurality of second scan lines, a plurality of data lines, and a plurality of pixel circuits; and a drive circuit configured to drive the first scan lines, the second scan lines, and the data lines. Each of the pixel circuits includes: a light-emitting element; a drive transistor configured to control a magnitude of an electric current that flows through the light-emitting element, a first compensation transistor having a control terminal connected to an associated one of the first scan lines; and a second compensation transistor having a control terminal connected to an associated one of the second scan lines. The first and second compensation transistors are connected in series and disposed between a control terminal and a conduction terminal of the drive transistor, the conduction terminal leading to the light-emitting element.
