Abrégé
(EN)
The disclosed polarizer comprises at least one substrate made of a birefringent material, and a polarizing plate located on the substrate. The substrate possesses anisotropic property of positive A-type and has a slow optical axis parallel to the substrate surface. The polarizing plate possesses anisotropic absorption of the electromagnetic radiation in at least one subrange of the visible spectral range, and a transmission axis of the polarizing plate and the slow optical axis of the substrate are directed substantially parallel to each other.

L'invention concerne un polariseur comprenant au moins un substrat constitué d'une matière biréfringente et une plaque de polarisation qui est disposée sur ce substrat. Ledit substrat possède une propriété anisotrope de type A positif et présente un axe optique lent s'étendant parallèlement à la surface du substrat. La plaque de polarisation effectue une absorption anisotrope du rayonnement électromagnétique dans au moins un sous-domaine du domaine spectral visible. De plus, un axe de transmission de la plaque de polarisation ainsi que l'axe optique lent du substrat sont sensiblement parallèles l'un à l'autre.
