Abstract:
The present invention provides a liquid crystal composition for forming a polymer layer capable of keeping high voltage holding ratio. The liquid crystal composition in an aspect of the present invention contains a liquid crystal material and one or more kind monomers and, at least one of the monomers is a compound produced by further bonding a hydrocarbon group with 12 carbon atoms or more to a compound produced by bonding two polymerizable groups to a cyclic aliphatic compound or aromatic compound with 6 carbon atoms or more.
