A method for manufacturing a display device includes providing a preliminary display device including a display module, an optical layer disposed on a first surface of the display module, a first protective film disposed on the optical layer, a second protective film disposed on a second surface of the display module, a first adhesive layer disposed between the optical layer and the first protective film, and a second adhesive layer disposed between the second protective film and the display module, forming a mask layer on the first protective film by irradiating a first laser light on the first protective film along a first processing line, and cutting the preliminary display device at an outer periphery of the second processing line by irradiating a second laser light on the first protective film along a second processing line positioned at an outer periphery of the first processing line.

Manufacturing method of display device and display device manufactured by the method

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.

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°.

A dummy removal device includes a picker picking a point of a dummy portion of a preliminary display module and moving in a first moving direction to separate a first portion of the dummy portion from the preliminary display module; and a separator disposed adjacent to the separated first portion and moving in a second moving direction intersecting the first moving direction to remove a second portion of the dummy portion from the preliminary display module, and the dummy portion is disposed around an effective portion of the preliminary display module.

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.
