SID Student Chapter Seminar: “Optically Isotropic Liquid Crystals for Electro-optical Devices”

SID Student Chapter Seminar: “Optically Isotropic Liquid Crystals for Electro-optical Devices”, Yasuhiro Haseba CREOL 102 Wednesday September 29, 2010 / 11:00am-12:00pm

Recently, a polymer stabilized blue phase (PSBP) which is one of optically isotopic liquid crystal phases has attracted general attention because it becomes a candidate state for LCD. To induce optically isotropic liquid crystal phases with a wide temperature range, an artificial control of coherence length of liquid crystals is key technology. Some works for controlling the coherence length reported so far have been introduced. In such works, PSBP and a polymer stabilized isotropic phase (PSIP) are focused. It is an advantage for them that they show large Kerr constants and quick response, and enable rubbing free process in LCD fabrication due to their optical isotropy. However there are some specific issues to be solved for mass production. Recent and future technologies to solve issues will be shown from the view point of materials development.


Yasuhiro Haseba received his B.S. degree in hydrocarbon chemistry from Kyoto University in 1992. After working at Sumitomo Bank Co., Ltd., he joined Chisso Co., Ltd., in 1993 and has studied liquid crystal materials until now. He also began his doctoral procedures in 2003 with Professor Hirotsugu Kikuchi at Kyushu University, where he was awarded his Ph.D. in 2006 for work on the optically isotropic liquid-crystalline composites. Since 2006, he has been concerning materials development for BP-mode LCD and now he is a leader of “blue phase project” in Chisso Co., LTD.
