Abstract
A light-scattering film includes a support; and a layer including a light-scattering particle and a light-transparent resin, wherein the light-scattering film satisfies following formulae (1) to (3) at the same time:nB435<nP435 Mathematical Formula (1)nB545<nP545 Mathematical Formula (2)0.9<(nP435/nB435)/(nP545/nB545)<1.005 Mathematical Formula (3)wherein nP435 and nP545 represent refractive indexes of the light-scattering particle at wavelengths of 435 nm and 545 nm, respectively, and nB435 and nB545 represent a refractive indexes of the light-transparent resin at wavelengths of 435 nm and 545 nm, respectively.
