OPTICAL SHEET OF OPTICAL LAMINATION FILM

摘要

An optical sheet of an optical lamination film is provided to improve luminance of a light and a viewing angle by using a prism sheet and a diffusion sheet including a regular or irregular defect. An optical sheet of an optical lamination film includes a diffusion sheet(300) and a prism sheet(100). The diffusion sheet includes a coating layer(330), a base layer(320), and an optical diffusion layer(310). The base layer is laminated on the coating layer. The optical diffusion layer is laminated on the base layer. The optical diffusion layer includes an optical diffusion agent(314) on a top part of the base layer. The prism sheet is laminated on a top part of the diffusion sheet. The prism sheet includes a plurality of defects.
