Title:
液晶表示装置の製造方法
Document Type and Number:
Japanese Patent JP4605978
Kind Code:
B2
Abstract:
The present invention provides a liquid crystal display device having uniform alignment of monostable ferroelectric liquid crystal, and a manufacturing method of the liquid crystal display device. The temperature range of a cholesteric phase or a chiral nematic phase of the phase sequence of the liquid crystal has a temperature width of not less than 3° C. After heating the liquid crystal to an isotropic phase once, the liquid crystal is cooled to room temperature (25° C.) at a cooling rate of 3, 5, 10° C./minute. An alignment treatment is performed by application of a DC voltage of not lower than 3 V, which is a sufficient voltage to obtain the effects of the alignment treatment, within a temperature range of ±3° C. from transition temperature at which the liquid crystal changes from the cholesteric phase to the chiral smectic C phase.
