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%).
摘要翻译：取向液晶的方法，包括固定在热板（21）和加热的液晶单元（1），其中的铁电液晶材料构成的液晶（12）电极基板之间密封的步骤（10 ，11）。衬底分别具有具有通过摩擦施加于其上的单轴取向的取向膜。压力由辊（未示出）施加到液晶单元，并进行上施加压力的单元的一部分被通过移动辊移动。此外，将液晶近晶A（SMA）相的相转变温度到一个手性近晶C（SmC的*）相和温度10℃以下的相变温度之间的温度范围内加热。经受上施加压力的单元的部分移动的方向相同的方向与摩擦的方向，从而以更高的产率实现液晶的取向C2。内所描述的温度范围内，通过相对于摩擦方向移动的方向上的电池的一部分，一个C2取向可以容易地以高收率（几乎100％）来实现的。
