Abstract

Disclosed is a multifunctional optical sheet for use in liquid crystal displays, which can exhibit appropriate hiding performance while realizing luminance equivalent to that of a conventional case in which a prism sheet is layered on a light diffusion member, thus reducing the number of sheets to be mounted in a backlight unit.
