Abstract

PURPOSE: To obtain a liquid crystal device which can be driven at a low voltage, does not need a polarizing plate, and can be made in a large size by forming a specified light controlling layer between two base materials which have an electrode layer and at least one of which is transparent.
CONSTITUTION: A nematic liquid crystal material (a) containing a compound (i) of formula I (wherein R1 is 1-10C straight-chain alkyl or straight-chain alkoxy; the group of formula II is a group of formula III or IV) and a compound (ii) of formula V (wherein R2 is 1-10C straight-chain alkyl: R3 is 1-12C straight-chain alkyl or straight- chain alkoxy; the group of formula VI is a group of formula VII or VIII) and a solution (b) comprising an ultraviolet-curing polymer-forming monomer or oligomer (iii) and, if necessary, a polymerization initiator, a chain transfer agent, a photosensitizer, a dye crosslinking agent, etc. (iv), are put between two base materials (A) which have an electrode layer and at least one of which is transparent, and then irradiated with ultraviolet rays through the transparent base material of component A to polymerize component (iii), thus forming between component A a light controlling layer (B) wherein a transparent solid substance comprising a polymer of component (iii) is dispersed to form a three-dimensional network in a continuous layer of component (a) accounting for at least 70wt.%.
