(57) [Summary] [Structure] General Formula (I) (In the formula, R 1 and R 2 ; an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, a substitution product thereof, R 3 ; H, CH 3 , X; -, -COO-, Y; -O-, -COO-, optionally forming a ring, -N-, n; an integer of 2 to 4) having a side chain type polymerizable compound and an electrode layer. At least one has two transparent substrates and a light control layer supported by the substrates, and the light control layer contains a liquid crystal material and a side chain type polymerizable compound represented by the general formula (I). A liquid crystal device containing a transparent polymer substance obtained by polymerizing a composition. [Effect] Compared with the conventional liquid crystal dispersion type or liquid crystal continuous layer type liquid crystal device, much lower voltage driving is possible, Since the transparent-opaque contrast is high and the threshold voltage is clear, time-division driving is possible. In addition, a substance that can be used as a raw material for synthesizing the side chain-type polymerizable compound is often industrially produced, and the raw material cost is reduced. |
