Abstract:
1. A polarizer for a multi-domain vertical alignment liquid crystal display, comprising: a first protective film; a first linear polarizing film; a first biaxial film; a first quarter-wave film; a second quarter-wave film; a second biaxial film; a second linear polarizing film; and a second protective film; wherein the first protective film, the first linear polarizing film, the first biaxial film, the first quarter-wave film, the second quarter-wave film, the second biaxial film, the second linear polarizing film and the second protective film are placed in order from a backlight source, an absorption axis of the first linear polarizing film is substantially perpendicular to an absorption axis of the second linear polarizing film, a slow axis of the first quarter-wave film is substantially perpendicular to a slow axis of the second quarter-wave film, the first quarter-wave film comprises a first narrowband quarter-wave film and a first narrowband half-wave film, and the second quarter-wave film comprises a second narrowband quarter-wave film and a second narrowband half-wave film the first narrowband half-wave film is placed between the first biaxial film and the first narrowband quarter-wave film, and the second narrowband half-wave film is placed between the second biaxial film and the second narrowband quarter-wave film.
