Abstract: 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°.

Abstract: A method for manufacturing an electronic apparatus, includes: providing a preliminary electronic module including an active area having a hole-forming area, and a peripheral area adjacent to the active area; emitting a laser beam while rotating a laser source along a moving path defined along a boundary between the hole-forming area and the active area, the moving path being divided into a first section and a second section; and removing the hole-forming area from the preliminary electronic module to form an electronic module having a module hole. During a first rotation of the laser source along the moving path, the laser beam is not emitted on the first section, and the laser beam is emitted on the second section.
