ABSTRACT:
A liquid crystal display device produced through the steps of injecting a polymerizable monomer-containing liquid crystal composition between two substrates and, while applying a voltage between opposing transparent electrodes of the substrates, polymerizing the monomer, wherein the polymerizable monomer contained in the liquid crystal composition has one or more ring or condensed ring structures and functional groups bonded directly to the ring or condensed ring structure.The monomer is preferably represented by the following general formula:in-line-formulae description="In-line Formulae" end="lead"?P1-A1-(Z1-A2)n-P2in-line-formulae description="In-line Formulae" end="tail"?wherein P1and P2are acrylates or the like, A1and A2are 1,4-phenylenes or the like, Z1is —COO— or the like, and n is 0 to 2.
