Optically functional film

Abstract

Provided is an optically functional film that can contribute to the widening of the color gamut of an image display apparatus, the optically functional film being suppressed in brightness reduction and being excellent in durability. The optically functional film of the present invention includes: a resin layer; and a pressure-sensitive adhesive layer arranged on at least one side of the resin layer, wherein the resin layer and/or the pressure-sensitive adhesive layer contains, as coloring matters, a compound X represented by the general formula (I) or (II) and a compound Y having an absorption peak in a wavelength band in a range of from 400 nm to 700 nm, which are mixed with each other.
