摘要： In order to produce full-color dichroic polarizers, it is necessary to produce absorption bands with several absorption maxima. The absorption bands produced until now always have a simple band form which is determined by the form of the non-spherical particles deposited in the polarization layer. By briefly warming a partial layer of a layer that is provided with not totally relaxed non-spherical silver particles, an adjustment of a given axis ratio occurs only in said partial layer, while absorption bands with several absorption maxima can be produced by means of differently adjusted axis ratios in superimposed partial layers. Full-color polarizers can be produced by combining several such absorption bands. Said polarizer can be used for the production of displays.
