摘要：
[PROBLEMS] To provide a photopolymerization initiator having an extremely low possibility of contaminating liquid crystals, and a liquid crystal sealing material using such a photopolymerization initiator. [MEANS FOR SOLVING PROBLEMS] A liquid crystal sealing material comprising (a) a reactive photopolymerization initiator represented by the general formula (1) and (b) a photocurable resin: (wherein R1 represents a divalent straight chain, branched or cyclic lower alkylene group having 1 to 10 carbon atoms or an arylene group; R2 represents a divalent straight chain, branched or cyclic lower alkylene group having 1 to 10 carbon atoms or an arylene group; Ar represents an arylene group; R3 represents a hydrogen atom or a methyl group; X and Y respectively represent O or S; and Z is a hydroxyl group or a morpholino group).
