ABSTRACT:
A smectic liquid crystal, typically, ferroelectric liquid crystal is uniformly orientated as follows: a space is provided as a dummy region in an area outside a panel region where a liquid crystal inlet is placed; two substrates are overlapped and cut into panels of a desired size, leaving the panel region and the dummy region whereas the rest is cut off; a liquid crystal is injected with the dummy region left in the liquid crystal inlet portion; and, immediately after the liquid crystal is injected, the dummy region is cut off to carry out monostabilization treatment.
