Abstract
A Random Depolarization Film (RDF), a polymer film doped with birefringent microparticles, randomizes polarization of the light. This study analyzed depolarization effects of the RDF that contribute to realizing real-color displays. The first effect is to decrease a degree of polarization, which resolves a blackout problem of the displays viewed through polarized sunglasses. The second effect is to minimize the wavelength dependence of the depolarization, which improves a color change of the displays viewed through the polarized sunglasses. The third effect is to minimize the viewing-angle dependence of the depolarization. The displays with the RDF hardly shows any color change at wide viewing angles.
