Abstract: An optical sheet, a backlight unit including the optical sheet, and a liquid crystal display including the backlight unit may be provided. The optical sheet may include a reflective polarizing film, a first adhesive layer on one surface of the reflective polarizing film, and a first diffusion layer on the first adhesive layer. The first diffusion layer may include a first light transmitting material and a plurality of first diffusion particles provided therein. A difference between a refractive index of the first adhesive layer and a refractive index of the first light transmitting material is less than or equal to approximately 0.2.

Abstract: An optical sheet, a backlight unit including the optical sheet, and a liquid crystal display including the backlight unit may be provided. The optical sheet may include a reflective polarizing film, a base film on one surface of the reflective polarizing film, and a plurality of projections on the base film. The base film may include a first surface and a second surface opposite the first surface. A first thickness T1 is a distance between the first surface and the second surface and a second thickness T2 is a distance between the first surface and the second surface. The first and second thickness T1 and T2 satisfy the following equation: 0.1 μm≦|T1-T2″≦10 μm.
