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.
Claims4
A liquid crystal material, having a banana-like molecular shape including two rodlike portions derived from a rodlike compound, at least one of which exhibits liquid crystallinity, and a linking portion derived from a compound selected from an alkyl alcohol compound represented by the formula:
- HO—(CH2)n—OH, wherein n is an odd number, a cycloalkyl compound, a heterocyclic ring compound and a nonlinear compound selected from a substituted or non-substituted alkyl ether, a substituted or non-substituted alkyl ketone, and an ethylenically unsaturated hydrocarbon group.
A liquid crystal material, having a conical molecular shape including at least three rodlike portions derived from a rodlike compound, at least one of which exhibits liquid crystallinity, and a linking portion derived from a compound selected from an alcohol compound, a ring compound and a nonlinear compound.
