ABSTRACT:
A liquid crystal display apparatus has a matrix of ferroelectric liquid crystal pixels which perform gradation display under active matrix driving. Each pixel is provided with a sub-capacitance for eliminating the influence of noise introduced through parasitic capacitance of a driving thin film transistor. The ferroelectric liquid crystal has a spontaneous polarization value P.sub.S [C/cm.sup.2 ] expressed by the following formula:
