Liquid crystal device

A liquid crystal device comprising a liquid crystal layer, wherein the liquid crystal layer comprises:

• a polymer network of a precursor comprising a silicon compound;
• and
• a liquid crystal compound present in a state dispersed in the polymer network, and
• an alignment film disposed adjacent to the liquid crystal layer,
• wherein the liquid crystal device further comprises polarizing layers disposed at both sides of the liquid crystal layer,
• wherein the light absorption axes of the two polarizing layers form an angle ranging from 80° to 100° with respect to each other, and the liquid crystal layer is initially aligned to form an angle ranging from 40° to 50° with respect to the light absorption axes of the two polarizing layers,
• wherein the liquid crystal device is driven in a normally transparent mode,
• wherein a haze is 10% or less and a light transmittance is 80% or more in a transparent mode of the liquid crystal device,
• wherein the silicon compound is represented by the following Formula 1 or 2, and
• wherein the liquid crystal compound is present in the liquid crystal layer in a state in which the liquid crystal compound is ordered in an initial state in one direction:
• where in Formula 1 or Formula 2, n is an integer ranging from 0 to 10, m is an integer ranging from 2 to 8, X is —O— or —NW—, and R1 to R6 are each independently an alkyl group, an alkoxy group, an aryl group, a polymerizable functional group, -A-R7 or -L-Si(R8)p(R9)(3-p), wherein A and L are each independently an alkylene group, an alkynylene group, an arylene group, an alkenylene group, an alkylidene group, —O— or —NW—, R7 is an alkyl group, an alkoxy group, an aryl group or a polymerizable functional group, R8 is a polymerizable functional group, R9 is an alkyl group, an alkoxy group or an aryl group, p is an integer ranging from 0 to 3, and W is hydrogen or an alkyl group.
