ABSTRACT:
An electronic circuit, a driving method for an electronic circuit, an electro-optical device, a driving method for an electro-optical device, and an electronic apparatus are provided to reduce the dispersion of the threshold voltages of transistors. A driving transistor, first and second switching transistors, an adjustment transistor, a coupling capacitor, and a holding capacitor form a pixel circuit. The threshold voltage of the adjustment transistor is applied to the gate of the driving transistor. According to various embodiments, the luminance gradation of a display element, such as an organic EL element, can be precisely controlled according to a data voltage.
