Beschreibung
Zusammenfassung:	The invention is to develop a color polarizing plate with a support, the polarizing plate having both good brightness and polarizing efficiency for a blue channel (for blue light). The color polarizing plate with a support for a liquid crystal projector comprises a polarizing plate containing a stilbene type water-soluble azo dye as a dichroic molecule and a support, wherein the polarizing plate has an average single transmittance of 39% or more and an average crossed transmittance of 0.4% or less at 420 to 500 nm and an average crossed transmittance of 4% or more at 650 to 780 nm.
