Polarizing plate, circularly polarizing plate, and method for producing polarizing plate

A polarizing plate comprising:

• an alignment film;
• and
• a polarizer layer including a dichroic coloring agent,
• wherein the polarizing plate has a plurality of through-holes that penetrate the alignment film and the polarizer layer,
• the polarizer layer is formed using a composition which contains a liquid crystalline compound and the dichroic coloring agent,
• the alignment film aligns the liquid crystalline compound,
• the polarizing plate is used for a display element having a self-luminous type light emitting elements,
• in a case where the polarizing plate is disposed on the display element, the plurality of through-holes are respectively disposed at positions corresponding to the light emitting elements,
• the polarizing plate further comprises a protective film laminated on the polarizer layer side via an adhesive layer,
• the adhesive layer is filled in at least a part of the through-holes, and
• an average diameter of the through-holes is 10 μm to 100 μm.
