Abstract
A liquid crystal electro-optic device. The liquid crystal electro-optic device comprises at least one liquid crystal cell comprising: a pair of substrates having a gap therebetween; a pair of electrodes, the pair of electrodes positioned on one of the substrates or one electrode positioned on each substrate; and a ferroelectric, oligosiloxane liquid crystal material disposed in the gap between the pair of substrates, the ferroelectric, oligosiloxane liquid crystal material exhibiting an I-♦ SmC* phase sequence wherein the liquid crystal electro-optic device is bistable in operation. The invention also involves a method for making a liquid crystal electro-optic device.
