Electric field aligned photo-polymer films for liquid crystal display
Oriented photopolymer films were obtained by using electric field alignment of the cinnamoyl side groups near the glass transition temperature of poly(vinyl)cinnamate (PVCN) followed by photo-polymerization using unpolarized UV light. In this way the induced anisotropy could be fixed and was subsequently shown to lead to a well aligned liquid crystal texture. The combination of electric field and UV light offers a solution to the pretilt angle problem for photo-aligned substrates.
