(57) [Summary] [Structure] A liquid crystal material comprising a ferroelectric liquid crystal or an antiferroelectric liquid crystal exhibiting a chiral smectic C phase, a chiral smectic C A phase or a smectic A phase in a temperature range of −40 to 80 ° C. [Effect] It can be used in a wide range of temperature conditions, can be used more than enough in a global area even if the temperature difference is large, and even with ferroelectric liquid crystals, uniform alignment can be easily obtained. Therefore, particularly as a liquid crystal material for a wobbling element, the contrast is improved, polarized light is not wasted, and higher resolution can be obtained. Moreover, the response speed is very fast, and it is possible to sufficiently drive at the video rate. |
