Abstract: A display device includes first and second substrates each including a short side and a long side, ground parts located on at least one of the short and long sides of each of the first and second substrates and including at least one first ground surfaces, which are perpendicular to opposing surfaces of the first and second substrates, and at least one second ground surfaces, which are provided at at least one edge of the second substrate to define an obtuse angle with reference to the first ground surfaces, and unevenness disposed on the first ground surfaces along a first direction, where the unevenness defines an acute angle with reference to a normal line to the opposing surfaces.

Abstract: An apparatus and a method for manufacturing a display device are provided. An apparatus for manufacturing a display device includes a first unit configured to remove impurities of a support substrate, a second unit configured to form a sacrificial layer on the support substrate, a third unit configured to form a flexible substrate on the sacrificial layer, and a fourth unit configured to form a display unit on the flexible substrate. The second unit includes a moving unit movable in a first direction to receive the support substrate, a first supply nozzle configured to spray a solution onto the support substrate to coat a graphene oxide layer, and a second supply nozzle configured to dry the graphene oxide layer coated on the support substrate while removing a portion of the graphene oxide layer, to form the sacrificial layer.

Abstract: A display device includes a first substrate defining a top surface thereof, a bottom surface thereof facing the top surface, and side surfaces thereof connecting the top and bottom surfaces to each other. The side surfaces included: a first side surface defined by: a first patterned surface including a first pattern of which a length thereof extends in a diagonal direction in a plan view of the first patterned surface, and a second patterned surface which extends obliquely from an upper end of the first patterned surface, the second patterned surface including a second pattern of which a length thereof extends in a perpendicular direction from the upper end of the first patterned surface in a plan view of the second patterned surface.
