Recently, the display of liquid crystal having the blue phase have been studied more intensively because it has many merits such as wide viewing angle without compensation films, very fast switching response time, and no need for the alignment layer and the rubbing process. First, we confirmed the feasibility of the blue phase liquid crystal display by means of polymer stabilization in the test cell. Even though we could get a wide temperature range that shows the blue phase, there were still problems such as the high operation voltage, hysteresis so on. In 2008, by developing and applying new technologies for improving these characteristics, we successfully fabricated a new kind of the liquid crystal display using the blue phase for the first time in the world.
