Lattice Orientation Dependence of Electro-optical Properties in Polymer-Stabilized Blue Phases

Abstract

Cholesteric blue phase I is a chiral liquid crystal phase having a body-centered cubic lattice with period of several hundred nanometers, and generally shows a colorful platelet texture composed of polycrystal-like structure with different lattice orientations. In this study, lattice orientation dependence of electro-optical properties in polymer-stabilized blue phase (PSBP) was investigated by combination of confocal laser scanning microscopy and microscopic electro-optical measurement system. A relationship between the lattice orientation of PSBP and the electro-optical properties was observed.
