Liquid crystal display apparatus, and driving circuit and driving method thereof

摘要

A liquid crystal display apparatus is composed of a plurality of pixels, a plurality of switches and a driver circuit for driving the plurality of switches. Each of the plurality of pixels is provided with a liquid crystal element in which a liquid crystal layer is sandwiched between a pixel driving electrode and a common electrode confronting with each other, a first sampling and holding circuit, a second sampling and holding circuit and a switching device. The switching device switches a positive image signal voltage and a negative image signal voltage, and supplies the positive and negative image signal voltages alternately to the pixel driving electrode.
