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.

Abstract: The present invention is related to a retardation device for a liquid crystal display and comprises: an upper retardation device, which has a plurality of retardation layers; a lower retardation device, which has a plurality of retardation layers as well; a LC cell layer, which is between the upper retardation device and the lower retardation device. The present invention adopts a set of retardation plates organized by the upper retardation device and the lower retardation device to apply on a MVA-LCD (Multi-domain Vertical Alignment Liquid Crystal Display) with features of high contrast and wide view angles to promote the contrast and the view angle.

Abstract: A structure and generated method of a polarizer is provided in this present invention that comprises a black dye layer formed form a black dye. The black dye layer is located on a protective layer that absorbs an emissive light from a polymer film. Furthermore, a thickness of the black dye layer depends on the desirable saturation of absorbency. The view angle of a displayed apparatus could be improved by the structure of the polarizer in this present invention.
