A compound that helps achieve a high voltage holding ratio (VHR) of a liquid crystal composition, a liquid crystal composition that contains this compound, and a liquid crystal display element made with this liquid crystal composition. More specifically, a compound represented by general formula (Y), which has polymerizable groups and polar group(s). A liquid crystal composition containing one or two or more compounds represented by general formula (Y), each of which has polymerizable groups and polar group(s). A liquid crystal display element made with a liquid crystal composition that contains one or two or more compounds represented by general formula (Y), each of which has polymerizable groups and polar group(s).

Liquid crystal composition, liquid crystal display element and compound

Provided are a substrate that can exert an anchoring force causing liquid crystal molecules to be vertically aligned and a liquid crystal display device. The substrate of the present invention is to be used in contact with a liquid crystal composition containing liquid crystal molecules and an alignment aid having a polar group and having the function of causing the liquid crystal molecules to be aligned spontaneously. The substrate includes an insulating film having a contact surface to be in contact with the liquid crystal composition. The static contact angle of water on the contact surface at 25&#xb0; C. is 70&#xb0; or less and/or the surface free energy of the contact surface is 50 mN/m or more. The substrate is preferably a substrate in direct contact with the liquid crystal composition with no alignment film therebetween.

Substrate and liquid crystal display device

A problem to be solved by the present invention is to provide a liquid crystal composition excellent in vertical alignment and compatibility and to provide a liquid crystal display device produced using the same. The problem is solved by a liquid crystal composition containing one or two or more kinds of self-aligning polymerizable monomers and one or two or more kinds of polymerizable monomers (or polymerizable compounds) having a specific chemical structure, and a liquid crystal display device produced using the same, specifically a liquid crystal composition containing a polymerizable monomer represented by General Formula (I) and a spontaneously aligning monomer which has a chemical structure different from that of the polymerizable monomer represented by General Formula (I), and has a polar group, and a liquid crystal display device containing the same.
