Abstract
Temperature ranges and phase behavior of blue phases (BPs) are related with concentration of chiral dopant. However, it is difficult to observe the phase behavior of BPs with high chirality by using a polarizing optical microscope (POM), because they show no Bragg's reflection in visible wavelength region. In this study, we observed textures and phase behavior of BPs with high chirality by using ultra-violet (UV) POM while measuring a change in their dielectric constants in IPS cell, and made their phase diagrams.
