Abstract: Disclosed is a method for manufacturing ultra-thin glass. The method includes: patterning, on a mother glass substrate comprising a plurality of display cells and a dummy area surrounding the display cells, a cutting line having a shape corresponding to the display cells; forming a mother glass protective film on the mother glass substrate; forming a through-hole which corresponds to the cutting line by etching the mother glass substrate; and cutting bridges which are formed by the mother glass substrate and connect the through-holes.

Abstract: Provided is a display device. The display device includes a flexible substrate comprising an active area, and a non-active area surrounding a border of the active area; a thin-film transistor and a light-emitting element on the active area; an encapsulation unit over the thin-film transistor and the light-emitting element; a hole formed in the active area by removing a portion of the flexible substrate; a first common layer disposed on a side surface of the hole, extended from the light-emitting element and comprising same elements with the light-emitting element; and a tip protruding from the side surface of the hole. The first common layer disposed adjacent to the tip is disconnected from the light-emitting element.
