Abstract

A jig and a method of manufacturing a window are provided. A jig includes a lower plate having a plurality of cell regions and a peripheral region dividing the plurality of cell regions, an intermediate plate on the lower plate and in which a plurality of openings corresponding to the plurality of cell regions is defined, and an upper plate on the intermediate plate, and a glass substrate is fixed between the intermediate plate and the upper plate.

First claim

What is claimed is:

1. A method of manufacturing a window, the method comprising:
providing a glass substrate in which pre-cutting lines are formed in each of upper and lower outer surfaces thereof, the pre-cutting lines defining a plurality of window regions;
performing chemical etching on the glass substrate so as to separate the glass substrate, at the pre-cutting lines, into a plurality of windows corresponding to the plurality of window regions; and
collecting the plurality of windows corresponding to the plurality of window regions and separated from the glass substrate.

2. The method of claim 1 , wherein the chemical etching is performed while the glass substrate is fixed to a jig.

3. The method of claim 2 , wherein the jig is immersed in an etchant tank.

4. The method of claim 2 , wherein the jig comprises any of plastic, Teflon, silicone, or stainless steel.

5. The method of claim 2 , wherein the jig comprises:
a lower plate comprising a plurality of cell regions and a peripheral region dividing the plurality of cell regions;
an intermediate plate on the lower plate and comprising a plurality of openings corresponding to the plurality of cell regions; and
an upper plate on the intermediate plate,
wherein the glass substrate is fixed between the intermediate plate and the upper plate.

6. The method of claim 5 , wherein, after the chemical etching, the glass substrate is separated into the plurality of windows and dummy glasses corresponding to the intermediate plate.

7. The method of claim 6 , wherein the dummy glasses have an integral shape.

8. The method of claim 6 , wherein the upper plate and the intermediate plate are separated from the lower plate while being coupled to each other.

9. The method of claim 1 , wherein the pre-cutting lines are formed by irradiating the glass substrate with a laser beam.

10. The method of claim 1 , wherein depths of the pre-cutting lines are about 10% to about 20% of a thickness of the glass substrate.
