Abstract: A method of manufacturing a display panel includes forming a unit panel which includes a display unit provided on a substrate. The substrate of the unit panel is cut out in a form of a closed loop having a straight line portion and a curve portion that are connected to each other. The cutting out of the substrate of the unit panel includes cutting the straight line portion by a first cutting process using a first tool and cutting the curve portion by a second cutting process using a second tool that is different from the first tool.

Abstract: Systems and methods are described for a display panel and a method of manufacturing the display panel. The systems and methods may provide for a substrate having a first surface and a second surface that face each other, a display unit including an organic light-emitting device arranged on the first surface of the substrate; and a thin-film encapsulation layer arranged on the display unit to shield the display unit, wherein an edge of the first surface or an edge of the second surface are inclined with respect to the first surface or the second surface. The inclined surfaces are designed to prevent damage to the display due to fine cracks during the manufacturing process as the display panel is trimmed or cut from a single base member. A display panel having improved strength characteristics may be manufactured, as well.
