Liquid crystal display device |
摘要 |
The present invention provides a liquid crystal display device in which display defects are not easily generated even when an alignment film is not formed. The liquid crystal display device of the present invention includes a pair of substrates; and a liquid crystal layer that is held between the pair of substrates, wherein both substrates of the pair of substrates do not substantially include an alignment film, at least one substrate of the pair of substrates includes a polymer layer that controls the alignment of liquid crystal molecules adjacent thereto, the polymer layer is formed by polymerization of monomers of at least one kind included in a liquid crystal layer composition, and the monomers of at least one kind contain a compound represented by the following formula (1):;
(wherein A represents an acrylate group, a methacrylate group, an ethacrylate group, a vinyl group, or an allyl group; a represents 0 or 1; and m represents a natural number of 4 to 12). |

1. A liquid crystal display device comprising:
a pair of substrates; and a liquid crystal layer that is held between the pair of substrates, wherein both substrates of the pair of substrates optionally include an alignment film, at least one substrate of the pair of substrates includes a polymer layer that controls the alignment of liquid crystal molecules adjacent thereto, the polymer layer is formed by polymerization of monomers of at least one kind included in a liquid crystal layer composition, and the monomers of at least one kind contain a compound represented by the following formula (1):(wherein A represents an acrylate group, a methacrylate group, an ethacrylate group, a vinyl group, or an allyl group; a represents 0 or 1; and m represents a natural number of 4 to 12). |
