Liquid crystal element and method of producing the same

A method of producing a liquid crystal element, comprising:

• applying a liquid crystal alignment agent on a conductive film of a pair of substrates having the conductive film to form a coating film;
• forming a liquid crystal cell by arranging the pair of substrates on which the coating film is formed to face each other such that the coating films face each other with a liquid crystal layer interposed therebetween;
• and
• irradiating the liquid crystal cell with light in a state where a voltage is applied between the conductive films,
• wherein the liquid crystal layer includes a compound having an alkenyl structure and a compound having a terphenyl ring structure,
• wherein the compound having an alkenyl structure has a partial structure represented by the following Formula (1):
• *-A1-(X1)n (1)
• where in Formula (1), A1 is an (n+1)-valent alicyclic group, X1 is a group having an alkenyl structure, n is an integer of 1 to 3;
• and (*) represents a bonding position,
• wherein the compound having a terphenyl ring structure is at least one compound selected from the group consisting of Formulas (2-1), (2-3) and (2-6) to (2-10):
• where in Formulas (2-7) to (2-10), r is an integer of 1 or 2,
• wherein when the compound having a terphenyl ring structure does not include at least one compound selected from the group consisting of Formulas (2-7) to (2-10), the liquid crystal layer further includes a component having a radical polymerizable group that is at least one compound selected from the group consisting of Formulas (2-7) to (2-10), and Formulas (B1-1) to (B1-3):
• where in Formulas (2-7) to (2-10), r is an integer of 1 or 2, and in Formulas (B1-1) to (B1-3), R represents a hydrogen atom or a methyl group,
• wherein the liquid crystal alignment agent contains a polymer (P),
• wherein the polymer (P) is at least one selected from the group consisting of a polyamic acid, a polyamic acid ester and a polyimide, and the polymer (P) has at least one partial structure selected from the group consisting of a partial structure represented by the following Formula (p-1) and a partial structure represented by the following Formula (p-2):
• where in Formulas (p-1) and (p-2), R51 is a tetravalent organic group, R52 and R53 each independently represent a hydrogen atom or a monovalent organic group, and R54 is a divalent organic group, wherein at least one of R51 to R54 has at least one group selected from the group consisting of a radical polymerizable group, a photoinitiator group, a nitrogen-containing heterocycle, an amino group and a protected amino group.
