Abstract: A substrate-cutting method includes preparing a first substrate in which a plurality of first active areas spaced apart from each other and a first non-active area surrounding the first active areas are defined in a plane, forming an adhesive layer on the first substrate where the adhesive layer is disposed within the first active areas, disposing a second substrate in which a plurality of second active areas spaced apart from each other and a second non-active area surrounding the second active areas are defined in the plane, and cutting a cutting line of the second substrate, which corresponds to a boundary between the second active areas and the second non-active area, using a laser beam. The adhesive layer does not overlap the cutting line of the second substrate.

Abstract: The display device includes a display module which displays an image at a front surface of the display module and includes a rear surface, a folding area and a non-folding area extended from the folding area; and a supporter facing the rear surface of the display module and including a first portion corresponding to the non-folding area, a second portion corresponding to the folding area, and a boundary between the first portion and the second portion. The display module which is unfolded disposes the supporter bent at the boundary, and the supporter which is bent includes the first portion and the second portion together forming a curvature of the supporter having a center of curvature at the front surface of the display module.
