Liquid crystal display device for viewing angle enhancement film, protection with a viewing angle improvement feature film and a liquid crystal display device

摘要

PROBLEM TO BE SOLVED: To provide a viewing-angle increasing film for a liquid crystal display device, capable of striking a balance in a high degree between the increase of the viewing angle and the reduction of darkening of images occurring when the display is viewed from the front.;SOLUTION: The viewing-angle increasing film for the liquid crystal display device obtained by melt extrusion molding of a mixture of at least two kinds of incompatible polyolefin resins satisfies the following conditions (1) and (2) at the same time: (1) The transmittance of parallel rays ranges from 5 to 90%; and (2) The diffusivity (A) in the main diffusion direction ranges from 1° to 20°.;COPYRIGHT: (C)2011,JPO&INPIT
