Polarizing plate and image display device, and method for producing polarizing plate

Abstract

The present invention provides a polarizing plate which could suppress the reduction of the transmission in a high temperature environment. The polarizing plate of the present invention has a polarizing element with a dichroic pigment adsorbed and oriented on a polyvinyl alcohol resin layer, and a transparent protecting film laminated on at least one side of the aforementioned polarizing element, wherein the aforementioned polarizing element and the transparent protecting film are adhered by an adhesive layer formed by adhesive having a first compound and a second compound, and the first compound is at least one selected from the group of urea, urea derivatives, thiourea, and thiourea derivatives, and the aforementioned second compound is a compound having a nitroxide free radical or a nitroxide group.
