OPTICAL FILM, LIQUID CRYSTAL PANEL USING THE SAME, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided is an optical film for a VA mode liquid crystal cell of the multi-domain type which can improve luminance of white display at a low cost without lowering the display quality. The optical film (10) is used for a VA mode liquid crystal cell of the multi-domain type having a transparent polymer film (11), a polarizer (12), and an optical compensation layer (14) which are layered in this order. The optical film (10) further includes a ?/4 plate (13) which is arranged between the polarizer (12) and the optical compensation layer (14). The angle defined by an absorption axis of the polarizer (12) and a delay axis of the ?/4 plate (13) is set in a range of 45 plus/minus 5 degrees.
