Abstract

A cover glass printing pad, a method of manufacturing the cover glass and the cover glass are provided. The cover glass printing pad includes a jig portion, a body portion in which a first surface contacts the jig portion and at least a part of a second surface is parallel to the first surface and a pad portion including an outer frame portion disposed on at least one side of the body portion and protruding in a first direction perpendicular to the second surface.

First claim

What is claimed is:

1 . A method of manufacturing a cover glass, the method comprising:
providing a base member including a first area, a surface of which is parallel to a first direction, and a second area adjacent to the first area and not parallel to the first direction; and forming a first light blocking layer disposed on at least a part of the first area adjacent to the second area and a second light blocking layer disposed on at least a part of the second area and partially contacting one end of the first light blocking layer.

2 . The method of claim 1 ,
wherein the forming the first light blocking layer includes: bringing a first pad contacting the first area into contact with at least a part of the first area and transferring a first light blocking ink to a contact area; and drying the first light blocking ink.

3 . The method of claim 2 ,
wherein the forming the second light blocking layer includes: bringing a second pad contacting the second area into contact with at least a part of the second area and transferring a second light blocking ink to the contact area; and drying the second light blocking ink.

4 . The method of claim 3 ,
wherein the second pad includes a jig portion; a body portion in which a first surface contacts the jig portion and at least a part of the second surface is parallel to the first surface; and a pad portion including an outer frame portion disposed on at least one side of the body portion and protruding in a first direction perpendicular to the second surface, and a contact area between one protruding end of the outer frame portion and the base member includes at least the second area.

5 . The method of claim 3 ,
wherein the drying the second light blocking ink is performed at a temperature of about 150 degrees Celsius to about 180 degrees Celsius, and the drying the first light blocking ink is performed at a temperature of about 60 degrees Celsius to about 80 degrees Celsius.

6 . The method of claim 5 ,
wherein a third light blocking layer disposed on the first light blocking layer and recessed inward from both ends of the first light blocking layer is further disposed.

7 . The method of claim 6 ,
wherein the disposing the third light blocking layer includes, after the forming the first light blocking layer: transferring a third light blocking ink onto the first light blocking layer using the first pad; and drying the third light blocking ink.

8 . The method of claim 3 ,
wherein the first light blocking layer is disposed on the first area after the second light blocking layer is disposed.

9 . A cover glass, comprising:
a base member including a first area, a surface of which is parallel to a first direction, and a second area adjacent to the first area and not parallel to the first direction; a first light blocking layer disposed on at least a part of the first area adjacent to the second area; and a second light blocking layer disposed on at least a part of the second area and partially contacting one end of the first light blocking layer.

10 . The cover glass of claim 9 ,
wherein a width of the first light blocking layer is larger than a width of the second light blocking layer.

11 . The cover glass of claim 10 , further comprising:
a third light blocking layer disposed on at least a part of the first light blocking layer, wherein both ends of the first light blocking layer protrude from both ends of the third light blocking layer.

12 . The cover glass of claim 11 ,
wherein the first light blocking layer, the second light blocking layer, and the third light blocking layer are arranged to extend in a second direction crossing the first direction.
