摘要： There is provided a light diffuser which can alleviate glare of light emitted from a light source while preventing a decrease in brightness of the emitted light despite the presence of the light diffuser. The light diffuser, contains a thermoplastic resin and transparent particles added thereto. The light diffuser has a total light transmittance in a range of 50 to 85%, and a wavelength selectivity in a rectilinear light ratio in a range of 1.5 to 5.0, as obtained by following formulas (1)-(3): (wavelength selectivity in rectilinear light ratio)=(rectilinear light ratio of 550-nm light)/(rectilinear light ratio of 450-nm light) (1) (rectilinear light ratio of 550-nm light)=(rectilinear light transmittance for 550-nm light)/(total transmittance for 550-nm light) (2) (rectilinear light ratio of 450-nm light)=(rectilinear light transmittance for 450-nm light)/(total transmittance for 450-nm light) (3).

摘要： A light diffuser and its use are provided, which not only reduces a color change in a source light when the light diffuser is disposed on an optical path of a light source, but also has a good light transmission property and a good light diffusion property. The light diffuser contains a thermoplastic resin and transparent particles added thereto. The total light transmittance of the light diffuser is 75% or more. The degree of dispersion of the light diffuser is 2° or more, the degree of dispersion being defined as a transmission angle at which a light transmittance is 50% of a rectilinear light transmittance when light is emitted to a surface of the light diffuser in a direction normal to the surface. The difference between the rectilinear light transmittance at 460 nm and the rectilinear light transmittance at 580 nm of the light diffuser is 0.96% or less.
