Abstract

In this paper, we report the fabrication of high quality polymer walls by using a monomer containing fluorine (F‐monomer). Polymer walls with no phase retardation were fabricated by using photo‐polymerization induced anisotropic phase separation of the mixture composed of liquid crystal (LC) and F‐monomer. Thanks to the immiscibility of fluoride, we could form high quality polymer walls with no light leakage. We measured electro‐optic characteristics of a twisted‐nematic (TN) LC cell whose polymer walls were fabricated by using the F‐monomer, and the measurements were compared with that fabricated by using the monomer without fluorine.
