Patent number: 11892669Abstract: A polarizing plate and a display device including the same. The polarizing plate includes a retardation layer exhibiting ultraviolet blocking characteristics even in a state where the retardation layer does not include any ultraviolet absorber or light stabilizer. The polarizing plate can be used alone or in combination with an appropriate sunscreen or a light stabilizer as needed to selectively block ultraviolet rays in a region requiring blocking, without affecting display performance, such as color senses and image quality, of a display device. The polarizing plate can also be formed with a small thickness without requiring a separate ultraviolet blocking layer, and also has excellent durability, because the polarizing plate exhibits a certain ultraviolet blocking property even in the absence of an ultraviolet absorber or light stabilizer.Type: GrantFiled: November 4, 2019Date of Patent: February 6, 2024Assignee: LG CHEM, LTD.Inventors: Hyuk Yoon, Jun Won Chang, Jong Hyun Jung, Sun Kug Kim, Moon Soo Park
