Blue phase (BP) liquid crystals have a three-dimensional periodic structure, which appears between the cholesteric (Ch) and isotropic phases. In this study, we have found that the phase transition from the uniformly oriented Ch phase to the BP phase is utilized to obtain giant BPI single crystals and that they exhibit growth characteristics similar to those of crystalline solids. In addition, we succeeded in controlling the position of BPI nucleation using a photoalignment technique.
