ABSTRACT:
A ferroelectric liquid crystal device is described. The device comprises a pair of substrates, an electrode arrangement formed on the inside surface of the substrates, an orientation control surface provided on the inside surface of one of said substrates, and a blended ferroelectric liquid crystal disposed between the substrates. By suitably preparing the liquid crystal, multi-micro-domains are formed in the liquid crystal. By virtue of the multi-micro-domains, the contrast ratio and the response speed are significantly improved.
