Title TN LIQUID CRYSTAL ELEMENT, AND METHOD FOR PRODUCING SAME meetings
Abstract Provided is a TN liquid crystal element which is stable as a TN liquid crystal, and which has a fast response speed when being switched off. Also provided is a method for producing said TN liquid crystal element. The TN liquid crystal element is provided with: a pair of substrates, at least one of which is transparent, and which are arranged approximately in parallel; a pair of alignment films, the surface of which is subjected to alignment processing so that the liquid crystal molecules within a liquid crystal material would face the same direction, and which are disposed on the opposing surface in relation to the pair of substrates; and a liquid crystal layer which is disposed between the pair of alignment films, and which contains a liquid crystal material and a chiral agent. An angle (.alpha.) formed by the alignment processing direction of the pair of alignment films is 70 deg. to 110 deg., and said alignment processing direction is a direction which forms a uniformed twist structure when the liquid crystal layer is twisted as much as the abovementioned angle (.alpha.). Moreover, an STN liquid crystal having a stable torsion angle of .alpha.+180 ( deg.) in an electroless state is polymer-stabilized as a TN liquid crystal having a torsion angle of .alpha. ( deg.).
