要約
(EN)
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 (a) 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 (a). Moreover, an STN liquid crystal having a stable torsion angle of a+180 (DEG) in an electroless state is polymer-stabilized as a TN liquid crystal having a torsion angle of a (DEG).
