Publication number: 20240118475Abstract: A polarization film includes: a base substrate in which a folding axis and a stretched axis are defined; and a deformation portion located at an edge of the base substrate. The stretched axis forms an angle of less than about 45° with respect to the folding axis. The display device, in which a folding area at which a folding axis is located and a non-folding area neighboring the folding area are defined, includes a display panel; a first adhesive layer on the display panel; and a polarization film on the first adhesive layer, where a stretched axis is defined in the polarization film. An angle between the folding axis and the stretched axis is less than about 45°.Type: ApplicationFiled: December 22, 2023Publication date: April 11, 2024Inventors: Kuhyun KANG, Muhyun KIM, Geunwoo YUG, Seoin HAN
