Provided are a liquid crystal composition capable of achieving vertical alignment of liquid crystal molecules without using an alignment film through the action of a polymer having a polar group, and a liquid crystal display element that contains this composition. A nematic liquid crystal composition having negative dielectric anisotropy and containing a polar compound that has a polymerizable group as a first additive and may contain a polymerizable compound as a second additive, and a liquid crystal display element that contains this composition are used. L'invention concerne une composition de cristaux liquides apte à obtenir un alignement vertical des molécules de cristaux liquides sans utiliser de film d'alignement par l'action d'un polymère ayant un groupe polaire, et un élément d'affichage à cristaux liquides qui contient cette composition. Une composition de cristaux liquides nématiques ayant une anisotropie diélectrique négative et contenant un composé polaire qui a un groupe polymérisable en tant que premier additif et peut contenir un composé polymérisable en tant que second additif, et un élément d'affichage à cristaux liquides qui contient cette composition sont utilisés. 極性基を有する重合体の作用によって液晶分子の垂直配向が配向膜を用いないで達成可能な液晶組成物、この組成物を含有する液晶表示素子を提供する。　第一添加物として重合性基を有する極性化合物を含有し、第二添加物として重合性化合物を含有してもよい、負の誘電率異方性を有するネマチック液晶組成物、この組成物を含有する液晶表示素子を用いる。
