Description

ABSTRACT:
A liquid crystal display apparatus comprising: a liquid crystal cell in which ferroelectric liquid crystal is disposed between two electrode substrates disposed to face each other and an intersection portion between a scanning electrode group and an information electrode group respectively formed on the electrode substrates is made to be a pixel; a scanning signal applying device; and an information signal applying device, wherein the pixel has a threshold distribution with respect to a gradation information signal at the time of a scanning selection operation, the scanning signal applying device simultaneously applies scanning signals to a plurality of scanning electrodes in synchronization with an operation in which the information signal applying device applies the gradation information signal to an information electrode, and the scanning signals applied simultaneously have different waveforms.
