Abstract: Disclosed is a method for aligning polymer network liquid crystal. In the method, alignment of liquid crystal in a bulk state is controlled by means of an orientation power of polymer material itself which is formed by irradiating linearly polarized ultraviolet rays to monomer material having an orientation power, thereby achieving a transparent state at an initial state without an orientation layer. That is, Linearly polarized ultraviolet rays are irradiated to ultraviolet-hardening type monomers having an orientation power. Alignment of liquid crystal of a bulk state is controlled while the monomers are changed to polymers, thereby achieving an initial transparent state. The molecules of the liquid crystal are placed in disorder by a vertical electric field and the horizontal orientation power of a polymer chain.
