Title:

MOIRE FRINGE SUPPRESSION FILM, AND PRISM SHEET HAVING MOIRE FRINGE SUPPRESSION FUNCTION

Document Type and Number:

WIPO Patent Application WO/2010/029910

Kind Code:

A1

Abstract:

Disclosed is a moire fringe suppression film having an optical diffusion layer containing a resin binder and porous particles on one face of a light-transmissive substrate. The porous particles have a pore capacity of 1.00 to 2.00 ml/g and a content of 30 weight parts or less to 100 weight parts of the solid component of the resin binder. The moire fringe suppression film is disposed on the emission surface side of a prism sheet of a back light unit constituted such that the prism sheet has a prism surface which is so arranged as to face the emission surface side of an optical guide plate, whereby the moire fringe can be effectively suppressed while keeping a high front luminance of the back light unit. Furtheremore, a prism sheet having a moire fringe suppressing function, in which the moire fringe suppression film and the prism sheet are integrated, can be manufactured by forming a prism array on the opposite side across the light-transmissive substrate of the optical diffusion layer.
