ABSTRACT:
A high-resistance transparent electrode is bonded on the opposite surface of a first glass substrate from a second glass substrate, and a low-resistance transparent electrode is bonded on the opposite surface of the second glass substrate from the first glass substrate. A pair of deflecting angle control electrodes are fixed to the high-resistance transparent electrode in parallel. A liquid crystal orientation film covers the high-resistance transparent electrode and the deflecting angle control electrodes, and another liquid crystal orientation film covers the low-resistance transparent electrode. Spacers are disposed in parallel between the liquid crystal orientation films, and the cell formed by the liquid crystal orientation films and spacers is filled with a nematic liquid crystal. When the voltage impressed between the low-resistance transparent electrode and the high-resistance transparent electrode and to both ends of the high-resistance transparent electrode is varied, the potential gradient varies, and the refraction index gradient varies in the same way. When light passes through a liquid crystal having such a refraction index gradient, the light is deflected depending on the distribution of refraction indices. When the refraction index gradient is varied by varying the potential gradient, the angle of deflection varies.
