    摘要： An optical switching device comprising a first layer (1) having a first refractive index and having a first side where a coherent light is to be entered into the first layer and a second side opposite the first side, second and third layers (2,3) sandwiching the first layer, the second layer having a main surface, and electrodes (4,5) sandwiching the second and third layers for applying a voltage between the second and third layers, wherein a refractive index of the second layer can be changed from second to third and from third to second refractive indexes by an electro-optical effect using the voltage, the second refractive index being larger than the third refractive index, wherein the coherent light entering the first layer (1) is totally reflected by the second layer (2) when the second layer has the second refractive index, and at least part of the coherent light is transmitted through the second layer (2) toward the outside of the main surface of the second layer when the second layer has the third refractive index.

    摘要： A liquid crystal display device which comprises an orientation film and at least one charge transporting material doped in the orientation film, the charge transporting material and an amount thereof being sufficient to cause a leakage of an electric charge temporarily accumulated in the orientation film or a portion adjacent thereto, during an operation of the device, to thereby inhibit a formation of an electric bilayer in the device. Since the formation of an electric bilayer is inhibited, a generation of crosstalk and reduction of display characteristics such as memory properties of the LC display device can be effectively prevented.
