Document Type and Number:

WIPO Patent Application WO/2011/135854

Kind Code:

A1

Abstract:

Provided are an optical multilayered product, a polarizer, and a display device which attain high visibility and extremely high dark-room contrast. The optical multilayered product comprises a light-transmitting base and an optical functional layer superposed thereon, and is characterized in that at least one surface of the optical functional layer has surface irregularities, the optical functional layer having surface irregularities comprises a resin ingredient, an inorganic ingredient, and light-transmitting fine particles, the refractive index (nF) of the light-transmitting fine particles and the refractive index (nZ) of the resin ingredient satisfy the relationship nZ-0.015≤nF≤nZ+0.015, and the surface of the optical functional layer which has the surface irregularities has a distribution of inclination angles in which the proportion of areas having an inclination angle of 2.0º or more is 3-20%.
