Abstract

We have reduced driving voltage of a flexible ferroelectric liquid crystal panel with polymer fibers and walls fastening two thin plastic substrates. The saturation voltage in the monostable V-shaped electrooptic property was decreased at several V, by dispersing fine sparse polymer fibers with small monomer concentration and by forming rigid polymer walls with strong ultraviolet light irradiation. The formation process and mechanism of the polymers were considered in detail. The rise and decay response times were measured, and the total response time was less than 1 ms. The outstanding features were applicable to a flexible large-size moving-image display panel with a direct-illumination- type bendable backlight sheet arraying small LED chips for field sequential color driving technique.
