To ensure safety, display devices that are used in automobiles need motion picture visibility at any situation. However, low temperatures cause conventional LCDs to respond more slowly, and this leads to motion blur. To eliminate this blurring, we have newly developed a high-performance OCB-LCD that responds quickly at low temperatures. We have speeded up the response time by using of an LC material that has a low rotational viscosity and by improving the bend transition. The new OCB-LCD has both a very fast response time and bend transition. The response time is a third that of the conventional OCB-LCD at -20°C, and does not require the present optical design to be changed. The bend transition time is about 1 second at -30°C. This speed is highly suitable for display devices used in automobiles.
