The present invention relates to photo-crosslinkable liquid crystal monomers with optical activity. The liquid crystal monomers contains one chiral center with an acrylate group or terminal diacrylate groups, and terminal dibenzene rings are introduced in order to extend its hard segment for the purpose of getting a wider liquid crystalline phase. By introducing the liquid crystal monomers, the room temperature nematic liquid crystal or the cholesteric liquid crystal may have a better mutual solubility and a wider, steadier structure of liquid crystal. The liquid crystal monomers have the following formula structure: 

Photo-crosslinkable liquid crystal monomers with optical activity

A liquid crystal composite is provided, which includes a liquid crystal compound and a nanoparticle. The liquid crystal compound is an optically compensated birefringence (OCB) liquid crystal compound. The nanoparticle has at least one acrylic functional group on the main chain or side chain thereof. The nanoparticle is 0.1-2 wt % by weight of the liquid crystal composite.
