摘要： An organic light emitting display device may include a flexible substrate, a common layer, and an encapsulation member. An undercut groove may be formed on the flexible substrate. The common layer may be disposed on the flexible substrate, may include an organic light emitting layer, and may be disconnected by the groove. The encapsulation member may be disposed on the common layer, and may cover the common layer.

摘要： A material-removing heater device including: a first terminal portion defining a first electrode; a second terminal portion defining a second electrode; and a heating portion which connects the first terminal portion to the second terminal portion, the heating portion heatable by a flow of electrical current from the first terminal portion to the second terminal portion to remove a portion of material of a display device. The heating portion defines a lower end surface of the material-removing heater device at which the material-removing heater device contacts the material of the display device, the heating portion disposes the lower end surface to have a concave shape, and the heating portion which is heated deforms the lower end surface from the concave shape to have a planar shape.

摘要： An apparatus for manufacturing a display device includes a mask assembly, the mask assembly including a silicon substrate having a first surface, a second surface opposite the first surface, and a first opening portion penetrating the first surface and the second surface, and a support substrate on the second surface, the support substrate having a second opening portion connected to the first opening portion. The first opening portion at the first surface is less in width than the first opening portion at the second surface.
