    摘要： A method of aligning a liquid crystal includes a step of fixing on a hot plate and heating a liquid crystal cell in which a liquid crystal composed of a ferroelectric liquid crystal material sealed between electrode substrates respectively having alignment films having applied thereto a uniaxial alignment by rubbing. According to the described method, a pressure is applied to the liquid crystal cell by a roller, and a portion subjected to an application of pressure is moved by moving the roller. Further, the liquid crystal is heated within a temperature range between a phase transition temperature of SmA phase SmC* phase and a temperature 10° C. below the phase transition temperature, and the portion subjected to an application of pressure is moved in the same direction as the rubbing direction, thereby achieving the C2 orientation at higher yield. Within the described temperature range, by moving the portion in an opposite direction to the rubbing direction, a C2 orientation can be always achieved at high yield (almost 100%). As a result, the C2 orientation can be surely achieved in the liquid crystal display element with ease.

    摘要： An electrode substrate is placed on a stage heated at temperature in a range of from 50.degree. to 200.degree. C. in such a manner that an alignment film of the electrode substrate faces upwards. Thereafter, a rubbing treatment is applied by a roller having the rubbing cloth wound therearound by moving a stage while rubbing the surface of the alignment film by rotating the roller in a state where the electrode substrate is sufficiently heated. Here, as the alignment film is softened by the described heat treatment, the rubbing process is facilitated. This permits a uniform C2 orientation without defects to be achieved in smectic liquid crystals.
