Abstract
A liquid crystal display device having a liquid crystal display cell disposed between a first electrode and a second electrode is disclosed. A circuit for applying an exciting voltage to the first electrode is also provided. An integrator integrates the exciting voltage to produce a mean DC voltage. The mean DC voltage is applied to the second electrode. If necessary, an impedance converter is provided to convert the impedance of the output from the integrator so that it is lower than that of the liquid crystal cell.
