A cholesteric liquid crystal mixture containing a compound represented by Z1—Y1-A1-Y3-M1-Y4-A2-Y2—Z2, a compound represented by Z3—Y5-A3-Y7-M2-P, and a tri- or higher functional polymerizable monomer suppresses deposition of a liquid crystal at the time of forming a film, exhibits a wide characteristic reflection bandwidth of the film. Z1 to Z3 represent a polymerizable group; A1 to A3 represent an alkylene spacer having a chain of 1 to 30 atoms; M1 and M2 represent (-T1-Y8)n-T2-; n indicates a natural number; T1 and T2 represent a hydrocarbon or heterocyclic ring; Y1 to Y5, Y7 and Y8 represent a single bond, —O—, —CO—, —O—CO—, —CO—O— or —O—CO—O—; and P represents a hydrogen atom or an alkyl group.
