  In this work the influence of cylindrical shape and alignment layers on light
reflection in Blue Phase Liquid Crystal (BPLC) is presented. For the first
time, the process of BP domains growth in a capillary is presented. The
cylindrical structure, its diameter and alignment layers change the
orientations of cubic blue phase (BP) domains and affect their growth. By using
temperature and external electric field the uniform structure was obtained. In
this study the ability of switching between BP I and chiral phase in a
capillary is also shown.
