The crosslinked liquid-crystalline polymer films with various contents of azobenzenes were prepared by photopolymerization of mixtures of an azobenzene liquid-crystalline (LC) monomer, a biphenyl LC monomer, and an azobenzene crosslinker. The crosslinked liquid-crystalline polymer films showed the photoinduced bending and unbending behavior upon alternate exposure to unpolarized UV light and unpolarized Vis light. It was found that the bending extents were different among the crosslinked LC
