A prepolymer composition for a polymer dispersed liquid crystal composite membrane, and a polymer dispersed liquid crystal composite membrane prepared by using the composition are provided to control a crosslinking density and a degree of polymerization, thereby reducing drive voltage and increasing contrast ratio. A prepolymer composition comprises 0.1-20 wt% of a multifunctional resin; 0.1-99 wt% of a diluent; 0.1-99 wt% of a crosslinking agent; and 0.1-99 wt% of a photoinitiator, wherein the multifunctional resin is an acrylate derivative compound having at least two functional groups; the diluent is at least one selected from an alkyl acrylate; the crosslinking agent is at least one selected from 1,6-hexanediol diacrylate and 1,6-hexanediol divinyl acrylate; and the photoinitiator is at least one selected from 2-hydroxy-2-methyl-1-phenylpropan-1-one and 2,4,6-trimethylbenzoyl diphenyl phosphine oxide.
