Claim Text:
1. A liquid crystal composition, comprising a liquid crystalline compound (A), and at least one nitrogen-containing compound (B) selected from the group consisting of compounds represented by formula (1) and compounds represented by formula (2), wherein R 1 is a hydrogen atom or a monovalent organic group that is bonded to the nitrogen atom bonded to R 2 and R 3 via a chain-shaped hydrocarbon group or an alicyclic hydrocarbon group, R 2 and R 3 are independently a divalent organic group that is bonded to the nitrogen atom bonded to R 1 via a chain-shaped hydrocarbon group, an alicyclic hydrocarbon group, or *—CO—R 4 — (wherein R 4 is a divalent chain-shaped hydrocarbon group or a divalent alicyclic hydrocarbon group, and * is a bond to the nitrogen atom bonded to R′), A′ is a nitrogen-containing heteroaromatic ring, X 1 is a cyclic ether group or a polymerizable unsaturated group, m is 0 or 1, and n is an integer of 1 to 3, provided that m+n≦3 is satisfied, a plurality of R 2 are either identical or different when a plurality of R 2 are present, a plurality of R 3 are either identical or different when a plurality of R 3 are present, a plurality of A 1 are either identical or different when a plurality of A 1 are present, and a plurality of X 1 are either identical or different when a plurality of X 1 are present, wherein A 1 is a nitrogen-containing heteroaromatic ring, and R 10 is a divalent organic group that is bonded to the primary amino group via a chain-shaped hydrocarbon group or an alicyclic hydrocarbon group.
