Surface stabilized ferroelectric liquid crystals (FLC's) have high potential for use in displays, image bars, and shutters. Because these materials are not absorbing, these devices will probably incorporate a polarizer and analyzer, permanently attached to the device, the polarizer attached at an angle corres-ponding to one of the two surface stabilized states and the analyzer at 90 degrees to the polarizer. With FLC in this state, there is no light passing through the cell. When the FLC is activated, the material is switched to the other surface stabilized state which now allows light to pass through the device.
