<P>PROBLEM TO BE SOLVED: To provide a white reflection film for improving brightness of the back light of a liquid crystal display. <P>SOLUTION: The white reflection film is provided with a coated layer containing spherical particle at least one side of the white film, wherein the particle size distribution of the spherical particles contained in the coated layer satisfies the condition (i) and (ii): (i) particle size distribution has two or more peaks, and (ii) coefficient of variation CV which is calculated on the basis of the every peak of the particle size distribution is 30% or less for all the peaks of the particle size distribution. Further, the white reflection film is provided with the coated layer, on at least one side of the white film, the coefficient of variation CV of which is 30% or less, and containing two or more kinds of spherical particles different in the mean volume particle diameter, and the particle size distribution of the spherical particles contained in the coated layer is provided with two or more peaks. <P>COPYRIGHT: (C)2009,JPO&INPIT |
