Abstract
A liquid crystal composition containing a polymerizable compound according to the present invention is used in a liquid crystal display element in which a liquid crystal alignment capability is provided through polymerization. The liquid crystal composition contains a polymerizable compound that polymerizes without a photopolymerization initiator or with an extremely small amount of photopolymerization initiator. Therefore, the alignment properties after the polymerization become more stable and the display characteristics do not degrade. Thus, the polymerizable compound is suitable as a practical component of the liquid crystal composition. A liquid crystal display element that uses the liquid crystal composition containing a polymerizable compound according to the present invention can be suitably used for VA and IPS liquid crystal display elements.
