Abstract:
Disclosed is a multi-functional monomer including a heat-curable functional group as well as a typical photoreactive group. In the multi-functional monomer, the photoreactive group is not chained to a main chain of a polymer. Thus, since it is possible to perform desirable alignment treatment even though polarized UV is radiated for a short time, the production time and the production cost are reduced and alignment regulating force of liquid crystals is increased, thereby increasing a dichroic ratio.
