Blue Phases (BPs) have three dimensionally ordered molecular alignments. Because of peculiar characteristics originating from these structures of BPs, they are expected to be applied for electro-optical devices and high-speed response display devices. However, an electric field-induced phase transition from BPs to a chiral nematic phase must be suppressed for such applications. The physical mechanism and dominating factors of the electric field-induced phase transition have not been much investigated so far. In this study, we investigated behavior of electric field-induced phase transition in BP by polarizing optical microscope observations, reflection spectra measurements and electric capacitance measurements.
