Mother panel for display panel and method of manufacturing display panel using the mother panel

摘要

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.

1. A mother panel for a display panel, the mother panel comprising:
a first mother substrate and a second mother substrate that are spaced apart from each other to face each other, each of the first mother substrate and the second mother substrate including at least one usable area that is usable as the display panel, and at least one unusable area that surrounds the usable area; a plurality of display panel patterns between the first mother substrate and the second mother substrate, the plurality of display panel patterns being 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 of at least one of the first mother substrate and the second mother substrate from being etched, wherein the etching stopping unit includes: a first etching stopping member that makes a seal between the first mother substrate and the second mother substrate; and a second etching stopping member that covers a lateral surface of at least one of the first mother substrate and the second mother substrate and covers the boundary area of the etching target surface of the at least one of the first mother substrate and the second mother substrate, the etching target surface being at an exterior of the mother panel and being orthogonal to the lateral surface.
