PURPOSE: An optical sheet is provided to be applied on a large size display device like TV since a haze is corrected by the refraction index and the filling rate of a micro lens layer. CONSTITUTION: An optical sheet comprises a base layer, a micro lens layer(10), and a light diffusing layer. The micro lens layer is formed on one side of the base layer. The light diffusing layer comprises an optical diffusion particle and a binder on the rear side of the base layer. The haze of the optical sheet is 40-100 %. The brightness rising rate is 1.2-2.3. |
