Abstract

See full text

A liquid crystal display apparatus includes systems of voltage applying devices for applying voltages to a liquid crystal and a controlling device for switching among these systems. The systems of voltage applying devices each have at least one non-linear switching element, and the controlling device has a memory portion for storing the switched state. With such a construction, electric power loss caused by one signal line having a relatively high frequency can be avoided by using another signal line having a relatively low frequency, thereby allowing a white, black, or gradation display with reduced power consumption.
