Abstract

A liquid crystal display device of the present invention includes: a pair of substrates for which a homeotropic alignment treatment is performed; a liquid crystal layer provided between the substrates; and a transverse electric field generating electrode capable of being driven in a matrix driving manner which is provided on at least one of the pair of substrates and is connected to external control means. A liquid crystal material contained in the liquid crystal layer is a liquid crystal material which, as a whole liquid crystal layer, generates spontaneous polarization by a piezoelectric effect.
