1. A polarizing element characterized in comprising a polyvinyl alcohol resin film adsorbing at least one dichromatic pigment that is a compound represented by formula (I) or a salt thereof as a free acid, and being stretched, wherein the polyvinyl alcohol resin has a degree of polymerization of 5,000 to 10,000:(wherein A represents a phenyl group or a naphthyl group having a substituent; R1-R6 each independently represent a hydrogen atom, a hydroxyl group, a lower alkyl group, a lower alkoxy group, a sulfo group, or a lower alkoxy group having a sulfo group; X represents an amino group optionally having a substituent, a benzoylamino group optionally having a substituent, a phenylamino group optionally having a substituent, a phenylazo group optionally having a substituent, or a naphthotriazole group optionally having a substituent;and m represents 0 or 1). |
