Blue phase liquid crystal and manufacturing method thereof

摘要

A manufacturing method of blue phase liquid crystal (BPLC), comprising steps of: a temperature control step which controls a temperature of a liquid crystal (LC) mixture within a range of a coexistence temperature of the blue phase and the isotropic phase; a temperature descending step which descends the temperature of the LC mixture to an operation temperature of the blue phase, wherein the operation temperature of the blue phase is higher than the phase transition temperature of the blue phase and the lower temperature phase; and a repeating step which repeats the temperature control step and the temperature descending step.
