Abstract
Disclosed is a liquid-crystal drive circuit having a simple configuration and being not susceptible to the characteristic of a device. The liquid-crystal drive circuit includes an auxiliary capacitor, applies a first voltage to a driving buffer, temporarily accumulates an output voltage of the driving buffer in the auxiliary capacitor, applies a voltage produced by subtracting the potential at the auxiliary capacitor from a second voltage to the driving buffer, and applies an output of the driving buffer onto a data bus.
