The dye molecules are dispersedly arranged in the polymer substrate. The dye molecules have a first absorption coefficient in a thickness direction of the polymer substrate. The dye molecules have a second absorption coefficient in a direction perpendicular to the thickness direction. A ratio of the first absorption coefficient to the second absorption coefficient is between 10 and 1000. A manufacturing method of the viewing angle limiting device and a display device including the viewing angle limiting device are also provided. The display device, the viewing angle limiting device, and the manufacturing method thereof provided by the invention have a large viewing angle filtering effect and have higher light transmittance in a viewing angle direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display device, viewing angle limiting device and manufacturing method thereof","description":"A viewing angle limiting device, including a polymer substrate and a plurality of dye molecules, is provided.
