1. An anisotropic scattering member formed into a sheet-like shape, comprising:
a light incident surface; and a light emitting surface, wherein each of the light incident surface and the light emitting surface includes a low refractive index area and a high refractive index area, wherein each of the low refractive index area and the high refractive index area extends in a thickness direction from the light incident surface to the light emitting surface, wherein the anisotropic scattering member satisfies
T(α)<10%, and−10 degrees≦α≦30 degrees, wherein α represents an angle between a normal direction of the light incident surface and an incident direction of light entering the light incident surface, and T(α) represents a transmittance at a position on an extension line of the incident direction with an incident angle (α). |
