| description | PROBLEM TO BE SOLVED: To provide an alignment treatment method which decreases the alignment defects after injection of smectic liquid crystals by effectively utilizing the temp. range of the antiferroelectric phase of these smectic liquid crystals and subjecting the smectic liquid crystals to cold-heat cycles. SOLUTION: The antiferroelectric liquid crystals are injected into an empty cell in a liquid crystal injecting stage S2. The liquid crystal cell is first arranged in a suitable cold-heat cycle test chamber in a cold-heat cycle stage S4. While the temp. of the antiferroelectric liquid crystals is maintained within a temp. range at which an antiferroelectric characteristic is exhibited by the prescribed cold-heat cycle conditions, the liquid crystal cell is alternately repetitively subjected to both treatments of heating and cooling. The liquid crystal cell is subjected to the cold-heat treatments in such a manner. |
