ABSTRACT:
To provide an electronic circuit, a method of driving the electronic circuit, an electro-optical device, a method of driving the electro-optical device and an electronic apparatus, capable of reducing deviations in threshold voltages of transistors. A pixel circuit20is constructed with three transistors of a driving transistor Trd, an adjusting transistor Trc and a switching transistor Trs, and two capacitors of a first capacitor C1and a second capacitor C2. Further, a source of the adjusting transistor Trc is connected to a voltage supply line VL for supplying a driving voltage Vdd through a control transistor Q in common with the sources of the adjusting transistors Trc of other pixel circuits, the voltage supply line VL being provided at the right end side of an active matrix part.
