Abstract

PURPOSE: To enable light reflection or light transmission to be controlled as desired by using a material which permits refractive index control through electric field and controlling the degree of the refractive index matching with the adjoining transparent material by an electric field.
CONSTITUTION: Transparent electrodes 3, 4 are provided to transparent support plates 1, 2. The (n) type nematic liquid crystal 9 whose refractive index to normal rays nearly coincides with the refractive indices of the support pltes 1, 2 is beforehand quasi-perpendicularly oriented with an inclination in a fixed direction by orientation treatment layers 5, 6a, 6b. Further, a light scatterng face 8 is formed on inside face of the plate 1. Perpendicular incident light 10 passes through the polarizing plate whose polarization direction coincides with the falling direction of the liquid crystal 9 and transmits like 11 with virtually no scattering at the boundary face between the liquid crystal and the support plates. When an electric field is applied from a power source 12, the liquid crystal 9 orients horizontally to the plates 1, 2. At this time, the refractive indices at the interfce of the liquid crystal and support plate do not match and the light 10 scatters like 13
