Classification: CPC G | IPC G

Claim 13:
14. A display device comprising:
a plurality of data signal lines connected to a data signal line drive circuit;
a plurality of scan signal lines connected to a scan signal line drive circuit and intersecting with the plurality of data signal lines; and
a plurality of pixel circuits at respective intersections of the plurality of data signal lines and the plurality of scan signal lines, wherein
each of the plurality of pixel circuits includes:
a current-driven light-emitting element;
a drive transistor configured to control an electric current for the light-emitting element;
a switching circuit; and
a first capacitive element and a second capacitive element both connected to the switching circuit,

the switching circuit connects the first capacitive element to a control terminal of the drive transistor in a first period that falls within a single frame period and connects the second capacitive element to the control terminal of the drive transistor in a second period that falls within the single frame period and that follows the first period, and
the control terminal of the drive transistor is connected to a constant voltage source via a constant voltage diode.
