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 display device includes a window; a display panel including: a flat portion corresponding to the display area, and a bending portion extending from the flat portion and at which the display panel is bendable; a circuit substrate connected to the display panel at the bending portion; and a protection film disposed facing the window with the display panel therebetween. The window and the display panel each include a first side surface corresponding to the bending portion, and remaining side surfaces except for the first side surface, and the remaining side surfaces of the window and the display panel are respectively aligned with each other to define a total planar area of the window being equal to a total planar area of the flat portion.

Abstract: A method for manufacturing a display device including a display panel having a folding area to be folded along a virtual folding axis and first and second non-folding areas adjacent to both sides of the folding area, and a window disposed on the display panel, the method including preparing a mother substrate having an effective area and a non-effective area divided by a cutting line, performing a first laser process along a first cutting line disposed in the first non-folding area, performing a second laser process along a second cutting line disposed in the second non-folding area, and performing a third laser process along a third cutting line disposed in the folding area, in which one end of the third cutting line overlaps a first end of the first cutting line, and the other end of the third cutting line overlaps a first end of the second cutting line.
