(과제) (수단) 액정 소자는, 기재(11, 12)와, 기재(11, 12)에 인접하여 배치된 유기층인 광학 이방성층(13)을 구비한다. 유기층은, 다음의 (A) 성분과 (B) 성분을 함유하는 액정 조성물을 이용하여 형성되어 있다. (A) 액정. (B) 탄소-탄소 불포화 결합을 갖는 중합성기와, 식 (1)로 나타나는 부분 구조 및 광 배향성기로 이루어지는 군으로부터 선택되는 적어도 1종의 배향성기를 갖는 중합체로서, 배향성기 중 및 배향성기와는 상이한 부분의 적어도 한쪽에, 실라놀기, 알콕시실릴기, 알코올성 수산기, 티올기, 카본산기, 아미노기, 술폰산기 및 인산기로 이루어지는 군으로부터 선택되는 적어도 1종의 극성기를 갖는 중합체. *-L1-R1-R2-R3-R4　...(1) To provide a liquid crystal element which exhibits excellent liquid crystal orientation even when a liquid crystal orientation film is unused.SOLUTION: A liquid crystal element comprises base materials 11, 12, and an optical anisotropic layer 13 which is an organic layer arranged adjacent to the base materials. The organic layer is formed using a liquid crystal composition that contains a component (A) and a component (B). (A): liquid crystal. (B): a polymer having a polymerizable group having a carbon-carbon unsaturated bond and at least one orientation group selected from the group consisting of a partial structure and an optical orientation group expressed by formula (1), the polymer having, in at least one of the orientation group and a part different from the orientation group, at least one polar group selected from the group consisting of a silanol group, an alkoxysilyl group, an alcoholic hydroxyl group, a thiol group, a carbonic acid group, an amino group, a sulfonate group and a phosphate group. *-L1-R1-R2-R3-R4 (1).SELECTED DRAWING: Figure 1
