Abstract
A molded article made of a light-diffusing resin composition which can color transmitted light, and use of the molded article are provided. In the molded article made of a light-diffusing resin composition (hereinafter “molded article”), the light-diffusing resin composition contains a thermoplastic resin and transparent particles which are dispersed in the resin and which have a volume-average particle size of 1-100 μm. The molded article has a total light transmittance of 85% or higher, and a degree of dispersion of 20° or less, wherein the degree of dispersion is 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 molded article in a direction normal to the surface. An average rectilinear light transmittance at wavelengths from 410-500 nm is greater than an average rectilinear light transmittance at wavelengths from 500-600 nm.
