Abstract
The present invention relates to a blue phase (BP) liquid crystal composition and to a method of stabilizing a blue phase state of a liquid crystal material. Furthermore, the present invention relates to a method of lowering the operating voltage of a liquid crystal material. Moreover, the present invention relates to a blue phase crystal material stabilized by the method according to the present invention or having an operating voltage that is lowered by the method according to the present invention. Also, the present invention relates to a liquid crystal cell comprising a blue phase liquid crystal material and to a liquid crystal display comprising a blue phase liquid crystal material. The present invention furthermore relates to a method of broadening that stability temperature range of a liquid crystal material in its blue phase state.
