Abstract
A polarizing plate including a substrate and a polarizer is provided. The polarizer has a polarizing layer having a thickness of 5 μm or less in which a dichroic dye is oriented. The absorbance in the absorption axis direction (A) of the polarizer at a wavelength of 380 to 760 nm is 0.3 or more and 1.5 or less, and the absorbance in the transmission axis direction (A) is 0.001 or more and 0.15 or less.
