Abstract:
1. A luminance enhancement film, comprising: an optical substrate, which comprises a light input surface and a structured light output surface at two opposite sides of the optical substrate; and a support substrate, which comprises a unitary body having a light input surface and a light output surface at two opposite sides of the unitary body, wherein the light output surface of the unitary body faces the light input surface of the optical substrate; wherein a plurality of particles are dispersed in at least one of a first surface region at the light input surface of the unitary body and a second surface region at the light output surface of the unitary body, wherein the first surface region has a first thickness substantially less than the thickness of the unitary body and the second surface region has a second thickness substantially less than the thickness of the unitary body.
