| Research Abstract |
The blue phase stabilization is explained by the large molecular biaxiality. However, no correlation exists between the helical twisting power and the BP temperature range. We prepared a host liquid crystal of a practical nematic liquid crystal mixture and a small amount of a newly designed T-shaped compound. The host liquid crystal doped with a chiral compound produced room-temperature amorphous blue phase III (BPIII). An in-plane-switching cell containing the BPIII material exhibited high transmittance, submillisecond response, and hysteresis-free switching.
