THERMALLY ADDRESSED LIQUID CRYSTAL DEVICE ABSTRACT OF DISCLOSURE A visual display device is featured which uses a new thermal electro-optic effect to provide a dark image upon a ligher background. The display is capable of being multiplexed to a large number of rows. The device comprises a liquid crystal material mixed with a pleochroic dye of high order parameter. When the material experiences a rapid transition from a higher to a lower, smectic thermal phase, two different textures or light states are developed; a transparent state and a light absorbing state. The transparent state is developed by applying a sensitizing voltage to certain portions of the medium. The pleochroic dye absorbs the light passing through the unsensitized portions of medium to provide the dark image. Heating electrodes are made diffusely reflective so as to provide a visual display that has high contrast and wide viewing angle.
