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.

An optical film is a laminate of an absorptive dichroic polarizing plate and a brightness enhancement film.

摘要： A diffusing/polarizing member (1) is provided which comprises a laminate (1) of a reflective polarizer (12) which separates incident natural light into a reflected light comprising a polarized light and a transmitted light, and a diffusing layer (11), wherein the reflective polarizer and the diffusing layer, when viewed from a slantwise direction, have respective colors which are complementary. Also provided is a liquid crystal display having the diffusing/polarizing member. In this diffusing/polarizing member, the color of the reflective polarizer viewed from a slantwise direction is negated by the color of the diffusing layer, these colors being complementary, whereby the member as a whole can be reduced in coloration when viewed from a slantwise direction. Thus, a reflective, semi-transmitting, or another liquid crystal display reduced in display unevenness, e.g., coloration in viewing from a slantwise direction, can be provided.
