摘要： A method of aligning a liquid crystal includes a step of fixing on a hot plate (21) and heating a liquid crystal cell (1) in which a liquid crystal (12) composed of a ferroelectric liquid crystal material is sealed between electrode substrates (10,11). The substrates respectively having alignment films having applied thereto a uniaxial alignment by rubbing. A pressure is applied to the liquid crystal cell by a roller (not shown), and a portion of the cell 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 a smectic A (SmA) phase to a chiral smectic C (SmC*) phase and a temperature 10°C below the phase transition temperature. The portion of the cell subjected to an application of pressure is moved in the same direction as the rubbing direction, thereby achieving a C2 orientation of the liquid crystal at higher yield. Within the described temperature range, by moving the portion of the cell in an opposite direction to the rubbing direction, a C2 orientation can readily be achieved at high yield (almost 100%).
