Abstract
In a display backlight (120, 220, 420) a specular partial reflector (250, 450) is placed between a circular-mode reflective polarizer (242, 442) and an illumination device (230, 430). The specular partial reflector (450) recycles otherwise unused polarized light (468L) reflected from the circular-mode reflective polarizer (442) which results in an optimized backlight brightness. The main application of the backlight (120) is in liquid crystal displays (100).
