Abstract

We clarified that polymer networks generated in polymer wall formation increase a threshold voltage for switching of a ferroelectric liquid crystal (FLC) near the polymer walls, from electron/optical microscopy and electrooptic measurement of FLC/polymer composite films. The polymer walls were formed by ultraviolet light irradiation to an FLC/monomer solution through a photomask. The ultraviolet light spreading from the photomask formed the undesirable polymer networks near the polymer walls. The decrease in the light spreading angle and monomer concentration reduced the generation of the polymer networks, which improved the FLC switching behaviors with applied voltages.
