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.
