Display device and electronic apparatus

摘要

A sampling transistor in embodiments of the present invention is kept at the on-state with a time width shorter than one horizontal cycle, during the period from the rising of a control pulse supplied from a scanner to the falling of the control pulse, and samples a video signal Vsig from a signal line SL to write the video signal Vsig to a hold capacitor. A sampling transistor T1 has a double gate structure in which a pair of transistor elements are connected in common. This suppresses change in the threshold voltage of the sampling transistor.
