Abstract

A reflective cholesterol liquid crystal (CLC) display with a wide viewing angle is demonstrated using the phase-separated composite film (PSCOF) method. The PSCOF-based CLC is formed by periodic and gradient UV illumination, slow polymerization and phase separation of the LC and prepolymer mixture. The helical axis of CLC is aligned normal to the protrusion of the PSCOF structure, and the multi-domain CLC structure can provides a wide viewing angle and low color shift. The conformation of PSCOF was also verified by AFM and SEM. The multi-domain PSCOF-based CLC display is simple to fabricate and suitable for use in a low-temperature flexible plastic process.
