LIGHT DIFFUSING ELEMENT, MANUFACTURING METHOD FOR POLARIZING PLATE WITH LIGHT DIFFUSING ELEMENT, LIGHT DIFFUSING ELEMENT AND POLARIZING PLATE WITH LIGHT DIFFUSING ELEMENT OBTAINED BY THE METHOD

摘要

There is provided a method capable of producing an extremely thin light diffusing element, which has strong light diffusibility and in which backscattering is suppressed, at a low cost and with extremely high productivity. A method of producing a light diffusing element according to an embodiment of the present invention includes : mixing a matrix formation material containing a monomer of a resin component and an ultrafine particle component, light diffusing fine particles, and a solvent for dissolving the monomer; and polymerizing the monomer. A zeta potential of each of the light diffusing fine particles in a solution prepared by dissolving the monomer in the solvent is equal in sign to a zeta potential of the ultrafine particle component in the solution prepared by dissolving the monomer in the solvent.
