    • 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.
    • 本发明一般涉及用于显示装置的背光模块和结合其的液晶显示器,更具体地说,涉及用于产生具有单一极化状态的光的背光模块。 本发明提供了一种背光模块,其包括用于反射和去极化入射在所述光学腔的前表面上的光的光腔和包括多个层的多层偏振片。 所述多层偏振器面向光腔的前表面,并且这些层被布置成使得基本上平行于所述多层偏振器的透射轴的偏振光基本上透射,并且基本上正交的偏振的光基本上被所述 在可见波长范围的至少一个预定波长范围内的多层偏振器。 所述层中的至少一个包括在层中至少部分地形成三维结构的棒状超分子。 本发明还提供了一种液晶显示器,其包括根据本发明第一方面的液晶单元,前偏振器和背光模块。 背光单元的多层偏振片面向后面板,作为液晶显示器的背面偏振片。
