Abstract: A prepolymer composition for a reverse mode polymer dispersed liquid crystal composite membrane, and a reverse mode polymer dispersed liquid crystal composite membrane prepared by using the composition are provided to lower drive voltage and to increase contrast ratio. A prepolymer composition comprises 0.5-20 wt% of a multifunctional resin; 0.1-99 wt% of a diluent; 0.5-70 wt% of a photoinitiator; and the balance of a crosslinking agent, wherein the multifunctional resin is an acrylate derivative compound having at least two functional groups; the diluent is at least one selected from the group consisting of 2-ethylhexyl acrylate, stearyl acrylate, isooctyl acrylate, methoxy polyethylene glycol acrylate, phenoxy polyethylene glycol acrylate, 2-hydroxypropyl acrylate, and 3,5-difluorobenzyl acrylate; the photoinitiator is at least one selected from the group consisting of 2-hydroxy-2-methyl-1-phenylpropan-1-one, 2,4,6-trimethylbenzoyl diphenyl phosphine oxide, diphenyl 2,4,6-trimethylbenzoyl phosphine oxide, and 2,2-dimethoxy-2-phenylacetophenone; and the crosslinking agent is at least one selected from the group consisting of neopentyl glycol diacrylate, polyethylene glycol diacrylate, trimethylolpropane trimethacrylate, and tripropylene glycol diacrylate.
