Abstract
A pixel circuit with a source follower type connection is provided that corrects variation in threshold voltage of a driving transistor, reduces power consumption and realizes high resolution. The pixel circuit includes: a data line for supplying a data voltage; a power source line for supplying a power source voltage; a reference voltage line for supplying a reference voltage lower than the power source voltage; a plurality of control signal lines for supplying control signals; a light emitting element; a driving transistor; a capacitor; and a plurality of switching transistors. The circuit writes the data voltage through one end of the capacitor and subsequently connects the one end of the capacitor to the anode electrode of the light emitting element.
