LIQUID CRYSTAL DISPLAY OPERATING IN A VERTICALLY ALIGNED MODE
The present invention relates generally to the field of liquid crystal display devices and more particularly to a liquid crystal display device operating in vertically aligned mode (VA-mode) in which liquid crystal molecules having a negative dielectric anisotropy are aligned generally perpendicularly to a panel surface of the liquid crystal display. A liquid crystal display according to the invention comprises a liquid crystal cell (6) of a vertical alignment mode, at least one polarizer (2, 10) arranged on each side of the liquid crystal cell, and at least one compensating structure (3, 7) disposed between the liquid crystal cell and at least one of the polarizers. The polarizers have transmission axes (11, 18) which are perpendicular to each other.
The present invention relates generally to backlight modules for display devices and liquid crystal displays incorporating the same, and more particularly, to a backlight module for generating light with a single polarization state. The present invention provides a backlight module, comprising an optical cavity for reflecting and depolarizing light that is incident upon a front surface of said optical cavity and a multilayer polarizer comprising a plurality of layers. Said multilayer polarizer faces the front surface of the optical cavity and the layers are arranged in such a way that a light of polarization substantially parallel to the transmission axis of said multilayer polarizer is substantially transmitted and the light of substantially orthogonal polarization is substantially reflected by said multilayer polarizer in at least one predetermined wavelength subrange of the visible wavelength range. At least one of said layers comprises rod-like supramolecules forming at least partially a three-dimensional structure in the layer. The present invention also provides a liquid crystal display, comprising a liquid crystal cell, a front polarizer, and a backlight module according to the first aspect of the present invention. The multilayer polarizer of the backlight module faces the back panel and serves as a back polarizer of the liquid crystal display.
