摘要： The present invention pertains to the field of polarisation devices and may be used in lighting fixtures, in the production of glass for the building industry as well as in displays. This invention relates to a dichroic polariser that comprises a substrate and at least one layer for the dichroic absorption of electro-magnetic radiation. The polariser also comprises two reflective coatings, one of which at least is partially transparent, wherein the layer for the dichroic absorption of electro-magnetic radiation is placed between said reflective coatings. The widths and the materials of said absorbing layer and reflective coatings are selected according to conditions that provide, at the output of said dichroic polariser, an interference minimum of the absorption component for at least one wavelength. According to this invention, the efficiency of the dichroic polariser is increased due to the higher polarisation level of the electro-magnetic radiation as it exits said polariser, while maintaining a high transparency (reflection) ratio for the non-absorbed component.

摘要： The present invention relates to devices for displaying information and more precisely to liquid crystal displays (LCD), wherein said invention may be used in indication systems for various purposes as well as in optical modulators, light-modulation matrix systems, etc. The liquid crystal display of the present invention comprises a liquid crystal layer which is located between a front and a rear plate each bearing an electrode and a polariser. The display also comprises a dye-containing layer that includes a dye which is luminescent under the action of UV radiation at a wavelength of between 400 and 700 nm or a mixture of a luminescent dye and an absorbing dye. This invention provides better brightness and colour saturation of the image as well as a greater angle of vision of the LCD display as far as 180° thanks to the more efficient use of the radiation spectrum from a radiation source, particularly in the ultraviolet range.
