<p>PURPOSE:To obtain the stabilized orientation of the titled cell in two directions by sealing the liquid crystal between the substrates after rubbing the substrates in at least two directions. CONSTITUTION:The one of the substrates 13 is rubbed in the two directions 16, 17 at an angle of 2theta. The titled angle theta of the molecule of the ferroelectric liquid crystal 15 in the working temp. range of the liquid cell is preferably theta(the tilt angle is an angle of inclining the long axis of the molecule against a vertical direction of the smectic layer). Another substrates 14 may be rubbed or not. If the pair of the substrates 13, 14 are rubbed, the substrates 13, 14 are combined so as to be the directions 16, 17 of rubbing the substrates 13,14 same each other in a cell formed by countering the substrates 13, 14. Thus, the orientation having the good ferroelectric liquid crystal is obtd. The two stable namely the bistable states of the cell may be realized by changing a polarity of the voltage.</p> |
