Abstract

An apparatus for manufacturing a display device includes a first jig including a first side, the first side having a concave groove for receiving a cover window, wherein the cover window includes a first planar portion, a first curved portion and a second curved portion, wherein the first and second curved portions are disposed at opposite ends of the first planar portion in a first direction, a second jig including a planar side for receiving a display panel, wherein when the second jig is moved in a second direction crossing the first direction with the display panel on the planar side, the display panel is disposed between the first and second curved portions of the cover window, and a pair of third jigs for supporting the first and second curved portions of the cover window.

First claim

What is claimed is:

1. A method for manufacturing a display device, comprising:
bending opposite ends of a display panel in a first direction to curve the opposite ends;
providing a cover window including a first planar portion and first curved portions disposed at opposite ends of the first planar portion in a first direction;
moving the display panel in a second direction crossing the first direction to dispose the display panel between the first curved portions of the cover window;
bonding the first planar portion of the cover window to the display panel; and
pressurizing the opposite ends of the display panel in the first direction to bond the opposite ends of the display panel to the first curved portions of the cover window, respectively,
wherein the first direction and the second direction are substantially parallel to the first planar portion.

2. The method of claim 1 , wherein the first direction is orthogonal to the second direction.

3. The method of claim 1 , wherein a radius of curvature of a portion of each of the curved opposite ends of the display panel is equal to or less than a radius of curvature of a corresponding first curved portion of the cover window.

4. The method of claim 1 , wherein the display panel is pressurized in a third direction that is orthogonal to the first direction and the second direction to bond the first planar portion of the cover window to the display panel.

5. The method of claim 1 , wherein the cover window further includes a second planar portion extending from a first end of one of the first curved portions,
wherein the first end of the one of the first curved portions is opposite to a second end of the one of the first curved portions, and the first planar portion extends from the second end of the one of the first curved portions.

6. The method of claim 5 , wherein a cross-section of at least one of the first curved portions is a quarter circle.

7. The method of claim 5 , wherein the cover window further includes a second curved portion extending from the second planar portion.

8. The method of claim 7 , wherein a cross-section of the second curved portion is a quarter circle.

9. The method of claim 7 , wherein the cover window further includes a third planar portion extending from the second curved portion.

10. The method of claim 1 , wherein a cross-section of at least one of the first curved portions is a half circle.

11. The method of claim 10 , wherein the cover window further includes a second planar portion extending from one of the first curved portions.
