    • An electrooptical solid element comprises a formed resin composition comprising a low molecular polar substance having a Kerr type electrooptical effect, and an organic polymer substance compatible with the low molecular polar substance. The formed resin composition is prepared by a method such as melt mixing on rollers, or dissolution in a common solvent followed by evaporation of the solvent. This formed resin composition is prepared in various shapes such as a polygon, a film, a prism and a polygonal pole. At least a pair of electrodes are provided on the surfaces of the formed resin composition, and further at least one of the electrodes may can be made of a transparent material.
    • 电光固体元件包括形成的树脂组合物,其包含具有克尔型电光效应的低分子极性物质和与低分子量物质相容的有机聚合物物质。 所形成的树脂组合物通过诸如在辊上熔融混合或溶解在普通溶剂中然后蒸发溶剂的方法制备。 这种形成的树脂组合物被制备成各种形状,例如多边形,薄膜,棱镜和多边形极。 至少一对电极设置在所形成的树脂组合物的表面上,并且另外至少一个电极可以由透明材料制成。
