Abstract: Systems and methods are provided for manufacturing a window from a transparent member. Forming the window may include forming of a groove by irradiating first laser light and removing a portion of a transparent member by irradiating second laser light focused at a depth of the groove. The first laser light may be emitted from a first laser generator and may be irradiated along an edge of a first area defined in a second surface of the transparent member. A second laser light may be focused to the depth of the groove, and thus a portion of the transparent member may be cut. The second laser light may be emitted by a second laser generator, and a focus of the second laser light may be located within the transparent member.

Abstract: A display device includes a display module, and a window which is disposed on the display module and in which a first non-folding region, a folding region, and a second non-folding region are sequentially defined in a first direction, wherein the window includes a base layer, a first hard coating layer disposed on an upper surface of the base layer, and a second hard coating layer disposed on a lower surface of the base layer, and the second hard coating layer includes a first portion overlapping the first non-folding region and the second non-folding region of the window, and a second portion overlapping the folding region of the window and having a hardness lower than a hardness of the first portion. Therefore, it is possible to provide a display device having desired surface hardness, impact resistance, and bending properties.
