Abstract: Polymeric films, which may be adhesive films, and display devices including such polymeric films, wherein a polymeric film includes: a first polymeric layer having two major surfaces, wherein the first polymeric layer includes a first polymeric matrix and particles. The first polymeric layer includes: a first a polyolefin-based low WVTR adhesive polymeric matrix having a refractive index n1; and particles having a refractive index n2 uniformly dispersed within the first polymeric matrix; wherein the particles are present in an amount of less than 30 vol-%, based on the volume of the first polymeric layer, and have a particle size range of 400 nanometers (nm) to 3000 nm; and wherein n1 is different than n2.
