Patent ID: 7956954

Claim:
An optical sheet, comprising: a reflective polarizing film; a first diffusing layer on the reflective polarizing film, the first diffusing layer including a resin and a plurality of first diffusion particles; and a first adhesive layer between the reflective polarizing film and the first diffusing layer, wherein, for a diameter D of the first diffusion particles corresponding to a maximum volume, a first percentage of a volume of the first diffusing layer having first diffusion particles with diameters between D−2 μm and D+2 μm is 40% to 80%, wherein the first diffusing layer includes substantially 10 to 50 parts by weight of the diffusion particle based on 100 parts by weight of the resin, wherein a thickness of the first adhesive layer is substantially 1 μm to 10 μm, and wherein D is substantially 3 μm to 6 μm.
