Abstract
A liquid crystal cell and liquid crystal display device include: two electrode substrates facing each other through a plurality of spacers; each electrode substrate being formed by superimposing a glass substrate, a transparent electrode and an alignment film; and an antiferroelectric liquid crystal being injected between alignment films; wherein, an alignment treatment is performed to each alignment film so that an angle of layer rotation of the antiferroelectric liquid crystal is defined within a predetermined allowable range.
