Zusammenfassung:	To provide a liquid crystal composition that suitably prevents deterioration of both heat-resistant VHR and light-resistant VHR, and a liquid crystal display element containing the liquid crystal composition.SOLUTION: A liquid crystal composition contains a liquid crystal molecule, a hindered amine compound, and a hindered phenolic compound. When a content of the hindered amine compound in the liquid crystal composition is A[ppm], and a content of the hindered phenolic compound in the liquid crystal composition is B[ppm], B/A is 10 or more.SELECTED DRAWING: None 【課題】対熱ＶＨＲ及び対光ＶＨＲの双方の低下を好適に防止した液晶組成物、及びかかる液晶組成物を用いた液晶表示素子を提供する。【解決手段】本発明の液晶組成物は、液晶分子と、ヒンダードアミン系化合物と、ヒンダードフェノール系化合物とを含有し、液晶組成物中に含まれるヒンダードアミン系化合物の量をＡ［ｐｐｍ］とし、液晶組成物中に含まれるヒンダードフェノール系化合物の量をＢ［ｐｐｍ］としたとき、Ｂ／Ａが１０以上であることを特徴とする。【選択図】なし
