Liquid-crystal displays and organic light-emitting diode displays cause blackout and color change problems when they are viewed through polarized sunglasses. The random depolarization film (RDF), a polymer film doped with calcite particles, improves the problems and contributes to the realization of real-color displays. However, the dopant particles in RDF scatter the light, which degrades the image sharpness. This study achieved the RDF that improved the image sharpness by utilizing directional forward scattering caused by micro-sized particles. In the conference, we will discuss the optimization of the dopant size in RDF for realizing real-color displays with the sharp image.
