Abstract
The transistor suffers the variation caused in threshold voltage or mobility due to gathering of the factors of the variation in gate insulator film resulting from a difference in manufacture process or substrate used and of the variation in channel-region crystal state. The present invention provides an electric circuit having an arrangement such that both electrodes of a capacitance element can hold a gate-to-source voltage of a particular transistor. The invention provides an electric circuit having a function capable of setting a potential difference at between the both electrodes of the capacitance element by the use of a constant-current source.
