    Abstract: PURPOSE: An optical laminate film for improving luminance is provided to increase availability of a light emitted in a light source by controlling a surface structure. CONSTITUTION: A laminate film(27) comprises a plurality of layers formed by two polymers having different refractive index. An embossing diffusion film(38) is laminated on one surface of the laminate film, and forms concavo-convex on a surface. A micro lens film(39) is laminated on the other surface of the laminate film. A micro lens is arranged in a surface(31-2) of the micro lens film. The embossing diffusion film has a retardation value of 1~25nm. A diameter of the micro lens is 20~200um. The micro lens film is formed by arranging a micro lens into a grating formation of regular triangle.
