Abstract

We have established a method to control the polymer aggregation structure of the PDLCs by using a micro-lens structure and irradiating them with uni-directionally diffused UV light. The micro-lens structure on the surface of the substrate produced an uneven illuminance distribution of UV light in the LC–monomer mixture, and the monomer was polymerized along the direction of UV light irradiation at positions where the UV illuminance was high and formed a layered structure. The proposed PDLCs could control the light diffusion distribution by the internal polymer aggregation structure and had a high diffusion efficiency without polarization dependency in the haze value.
