摘要： A reflective screen includes a light reflecting layer, and a light diffusing layer provided on the light reflecting layer. The light diffusing layer has the diffusion property that in one (A axis) of two perpendicular axial directions on a light diffusion plane, a luminance distribution curve versus incidence angle is asymmetric with respect to the zero-incidence-angle axis, and the side on which the incidence angle (half-luminance incidence angle) with half of a peak luminance on the A axis in the normal direction to the screen plane is small faces in a direction in which external light has the highest strength.
摘要翻译： 反射屏幕包括光反射层和设置在光反射层上的光漫射层。 光扩散层具有扩散特性，即在光扩散面上的两个垂直轴向的一个（A轴）上，亮度分布曲线与入射角相对于零入射角轴是不对称的， 其中在外部光具有最高强度的方向上，与屏幕平面的法线方向上的A轴上的峰值亮度的一半的入射角（半亮度入射角）小。

摘要： An optical element includes a base and a large number of structures arranged on the surface of the base, the structures being projections or depressions. The structures are arranged at a pitch shorter than or equal to a wavelength of light in a use environment. An effective refractive index in the depth direction of the structures gradually increases toward the base and has two or more inflection points.
