Abstract
A diffusing/polarizing member ( ) is provided which comprises a laminate ( ) of a reflective polarizer ( ) which separates incident natural light into a reflected light comprising a polarized light and a transmitted light, and a diffusing layer ( ), 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.
