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 substrate-cutting stage includes a main stage and a dummy stage spaced apart from each other with a cutting region interposed therebetween and that support a substrate. The main stage supports a first portion of the substrate, the dummy stage supports a second portion of the substrate, and the cutting region overlaps a to-be-cut portion of the substrate disposed between the first and second portions.

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°.
