摘要

PURPOSE: A diffusion film including a micro-lens pattern and an embossing pattern and a method for manufacturing the same are provided to obtain the high brightness by including the both of a diffusion function and a light collecting function. CONSTITUTION: A diffusion film(10) includes a light incident surface and a light emit surface. A plurality of micro-lenses(13) are arranged on the light emit surface. The micro-lenses are integrated into the diffusion film. An embossing pattern is formed on spaces(14) beside micro-lenses. The micro lenses with a hemisphere shape collect light. The embossing pattern diffuses the light. The diffusion film is composed of a thermoplastic resin material.
