    摘要: This invention relates to methods for preparing photo-patterned mono- or polychromatic, polarizing films. The polarizer can be pixelated into a number of small regions wherein some of the regions have one orientation of the principal neutral or color absorbing axis; and some other of the said regions have another orientation of the principal neutral or color absorbing axis. The axis orientation is determined by the polarization vector of actinic radiation and the multi-axes orientation is possible by a separated masked exposure. This polarizer can be placed on the interior substrate surface of the LCD cell.

    摘要: The present invention provides a method of forming a polarizing material comprising exposing a layer of dichroic material to activating light illumination to provide an ordered structure with a distinguished absorption axis and thus photo-induce polarization, and fixing the induced polarization by polymerisation of the dichroic layer. The present invention also provides novel polarizing formed thereby. By selectively exposing regions of the dichroic material to differing activating radiation, different regions with different polarization axes can be created. The polarizing material can also be provided with a coating or coatings to alter the spectral response, and a stack formed of a plurality if dichroic layers may be provided.

    摘要: A transflective liquid crystal display having at least one reflective region 122 and at least one transmissive region 121. The display comprises a first polarizer 5, a second polarizer 100 opposing the first polarizer 5, two twisted nematic liquid crystal layers 30, 60 between said first and second polarizers 5, 100 and a reflector 110 for reflecting light passing though the reflective region 122 of the display. The twisted nematic liquid crystal layers 30, 60 have opposite twist directions to each other. The second twisted nematic liquid crystal layer 60 improves the contrast of the display. The display may have a double cell arrangement, in which case there may be a single cell gap or a double cell gap. Alternatively, the display may have a single cell arrangement in which case the second twisted nematic liquid crystal layer is a temperature dependent retardation film 65.
