Title
(EN) METHOD FOR MANUFACTURING POLARIZER
(FR) PROCÉDÉ DE FABRICATION D'UN POLARISEUR
(KO) 편광자의 제조 방법
Abstract
(EN)
The present application provides: a polarizer which has a low orthogonal transmittance to visible light and a high orthogonal transmittance to near-infrared light; and a polarizing plate comprising same. Such a polarizer or polarizing plate can be applied to various devices using visible light and near-infrared light.
(FR)
La présente invention concerne : un polariseur qui a une faible transmittance orthogonale à la lumière visible et une transmittance orthogonale élevée à la lumière proche infrarouge ; et une plaque polarisante le comprenant. Un tel polariseur ou plaque polarisante peut être appliqué à divers dispositifs à l'aide d'une lumière visible et d'une lumière proche infrarouge.
