Abstract

PURPOSE:To obtain a stereospoctacles device preventing a reflected light incident to eyes from parts excepting the field of view by providing an antireflecting film around an opening of a supporting plate. CONSTITUTION:Crossed finger type electrodes 20, 20' and 30, 30' are provided on the surface and the rear of a solid plane plate 10 comprising a PLZT and further on the upper and lower parts polarizing plates, 4R, 5R intersecting at right angles each other are arranged. A solid plane plate 10 equipped with the electroces is held by a supporting plate 60, and around an opening part for field of view corresponding to the surface of this supporting plate, an antireflecting mirror or a nonreflecting plate 70 and a light absorbing plate 80 are provided. Here the reflection preventing film 70 is arranged to the side of an observer and the light absorbing plate 80 being arranged to the side where a light is made incident.
