SMECTIC LIQUID CRYSTAL HIGH-CONTRAST CONTROL OR DISPLAY DEVICE
摘要
The invention relates to a liquid crystal control or display device that contains a chiral smectic liquid crystal mixture. The ratio DELTA / THETA of the angle between the rubbing direction and the smectic layer normal to the tilt angle is at least 0.41. The liquid crystal mixture preferably has the phase sequence I-N-C and the tilt angle THETA at 25 DEG C ranges from 19 DEG to 39 DEG .
