Abstract

A method of fabricating a cover glass includes preparing a base member including a first area and a second area, wherein a surface of the base member is substantially parallel to a direction in the first area and is inclined with respect to the direction in the second area, and forming an ink layer on the surface of the base member in the second area, and forming a first print layer by removing a portion of the ink layer and forming a second print layer on the first print layer.

First claim

What is claimed is:

1. A cover glass comprising:
a base member including a first area and a second area adjacent to the first area, wherein a surface of the base member is substantially flat throughout the first area and a surface of the base member in the second area is inclined with respect to the surface of the base member in the first area;
a first print layer disposed on the surface of the base member in the second area; and
a second print layer disposed on the first print layer and spaced apart from a side surface of the first print layer, the side surface of the first print layer being adjacent to the first area, wherein
at least part of the side surface of the first print layer is recessed by a recessed portion toward the second print layer, and
the recessed portion being a void.

2. The cover glass of claim 1 , wherein a width of the first print layer is larger than a width of the second print layer.

3. The cover glass of claim 1 , wherein the at least part of the side surface of the first print layer includes a lower end portion that is inwardly recessed and in direct contact with the base member.

4. The cover glass of claim 1 , wherein
the first print layer and the second print layer extend along a side of the base member, and
a side of the first print layer adjacent to the first area has a partially curved shape.

5. The cover glass of claim 1 , wherein ink for the first print layer and the second print are applied by a pad technique and a portion of the first print layer and the second print layer are then removed.

6. The cover glass of claim 1 , wherein the void is an empty space.

7. The cover glass of claim 1 , wherein the first area corresponds to an image producing portion of a display device and the second area corresponds to a non-image producing portion of the display device.

8. A cover glass comprising:
a base member including a first area and a second area adjacent to the first area, wherein a surface of the base member is substantially flat throughout the first area, and a surface of the base member in the second area is inclined with respect to the surface of the base member in the first area;
a first print layer disposed on the surface of the base member in the second area; and
a second print layer disposed on the first print layer and spaced apart from a side surface of the first print layer, the side surface of the first print layer being adjacent to the first area, wherein
at least part of the side surface of the first print layer is recessed toward the second print layer, and
a thickness of the first print layer is smaller than a thickness of the second print layer.

9. A cover glass comprising:
a base member including a first area and a third area adjacent to the first area, wherein a surface of the base member in the first area is substantially flat throughout the first area, and a surface of the base member in the third area is bent downward from the surface of the base member in the first area;
a first print layer disposed on the surface of the base member in the third area; and
a second print layer disposed on the first print layer and spaced apart from a side surface of the first print layer, the side surface of the first print layer being adjacent to the first area, wherein
at least part of the side surface of the first print layer is recessed toward the second print layer,
the surface of the base member in the first area faces the surface of the base member in the third area in a direction perpendicular to the surface of the base member in the first area, and
the first print layer faces the surface of the base member in the first area in the direction perpendicular to the surface of the base member in the first area.

10. The cover glass of claim 9 , wherein a straight line parallel to a thickness direction of the base member in the first area passes through the base member twice at a location corresponding to the third area.
