摘要： An optical film having excellent light utilization efficiency and high brightness, and a liquid crystal display using the optical film. The optical film is formed by laminating integrally a brightness enhancement film (A) that separates natural light into transmitted light and reflected light and a collimating film (B) having an uneven portion on a surface thereof. Since an air interface is eliminated by the integral lamination of the brightness enhancement film and the collimating film, stray light is reduced, and the brightness enhancement film has an improved efficiency in reflecting and polarizing light; thereby, enhancing the brightness.
