Title:
液晶組成物の製造方法
Document Type and Number:
Japanese Patent JP4221678
Kind Code:
B2
Abstract:
The present invention provides a method for producing a liquid crystal composition which mixes two or more liquid crystal compounds, namely, a method for producing a liquid crystal composition, including conducting agitation or ultrasonic irradiation of two or more liquid crystal compounds without applying external heat, wherein at least one of the liquid crystal compounds has a melting point higher than 40° C., and a temperature at a start of the agitation or ultrasonic irradiation is not more than 40° C. The production method of the present invention enables a highly reliable, high-quality liquid crystal composition to be produced without the necessity for large-scale equipment such as a pressure reduction apparatus or heating apparatus. Accordingly, this method is extremely practical for the production of liquid crystal compositions that require a high level of reliability.
