Abstract: A mother panel for a display panel includes a first mother substrate and a second mother substrate that are spaced apart from each other to face each other, each of which includes at least one usable area that is usable as the display panel, and at least one unusable area that surrounds the usable area. The mother panel also includes a plurality of display panel patterns between the first mother substrate and the second mother substrate that are spaced apart from one another in the usable area, a seal pattern that adheres the first mother substrate with the second mother substrate and seals each of the plurality of display panel patterns, and an etching stopping unit that prevents an etchant from permeating between the first mother substrate and the second mother substrate and prevents a boundary area of an etching target surface from being etched.
