PROBLEM TO BE SOLVED: To provide a polymeric optical low pass filter having excellent double refractivity and sufficiently high transparency. SOLUTION: The polymeric optical low pass filter is composed of a copolymer obtained by a photopolymerizable liquid crystal composition comprising a polymerization modifier and a mesomorphism monomer consisting of 10 to 60 mass part of a specific compound (A), acrylic acid 4-(4-alkylcyclohexyl)phenyl, 30 to 80 mass part of a compound (B), 4-[ω-(propenoyloxy)alkoxy]benzoic acid-2-[4-[4-äω-(propenoyloxy)alkoxy}benzoiloxy]phenyl]ethyl and 3 to 30 mass part of a compound (C), 4-[6-(propenoyloxy)hexyloxy]benzoic acid 4-alkylphenyl.
