DYE-BASED POLARIZER, POLARIZING PLATE AND METHOD FOR PRODUCING THE DYE-BASED POLARIZER

摘要

Disclosed is a polarizing plate composed of a polarizer which is made of a hydrophilic polymer containing at least one dichroic dye and silicon or a silicon compound. The polarizing plate is suppressed in transmittance change even in a light resistance test using light of high intensity such as light of an ultra high-pressure mercury lamp. The polarizing plate is also suppressed in transmittance change in a heat resistance test. A liquid crystal projector exhibiting stable performance after long use can be obtained by using the polarizing plate.
