摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display in which the alignment state of a monostable ferroelectric liquid crystal is made uniform, and to provide a method for manufacturing the display.
SOLUTION: The temperature range of the cholesteric phase or the chiral nematic phase in the phase series of the liquid crystal is controlled to have ≥3°C temperature width. After the liquid crystal is heated to be transformed into the isotropic phase once, it is cooled to room temperature (25°C) at cooling rates of 3, 5, 10°C/minute. The alignment process is carried out by applying ≥3 V DC voltage which is a sufficient voltage to obtain the alignment effect in the temperature range of (the transition temperature from the cholesteric phase to the chiral smectic C phase of the liquid crystal)±3°C.

摘要： PROBLEM TO BE SOLVED: To provide a method for measuring the dichroic ratio of a dichroic dye used for a guest-host liquid crystal in a relatively short time. SOLUTION: A liquid crystal material consisting of a single component and having the solidification point at room temperature during the temperature descent is used as the host liquid crystal to dissolve a dichroic dye. The temperature conditions for the measurement are controlled in such a manner that the temperature is varied in the range of within 10 deg.C in the higher temperature side from the solidification point during the temperature descent of the host liquid crystal and that the absorbance in each of the vertical direction and the horizontal direction at each temperature is measured to obtain the dichroic ratio based on the measurement.
