Abstract
A polarizer used in liquid crystal display has two portions. A first portion of the polarizer is adjacent to a backlight source and has a first protective film, a first linear polarizing film, a first biaxial film and a first quarter-wave film from the backlight source to a multi-domain vertical alignment liquid crystal (MVA-LCD) cell. A second portion of the polarizer is on the other side of the MVA-LCD cell, and has a second quarter-wave film, a second biaxial film, a second linear polarizing film and a second protective film from the MVA-LCD cell.
