Abstract

A manufacturing apparatus of a display device that prevents generation of bubbles between a display panel and a cover window is presented. The apparatus includes a first jig that includes a first portion including a center and a second portion that includes a bend on at least one side of the first portion, and where a cover window is received; a second jig that faces the first portion of the first jig, wherein the cover window and a display panel are disposed between the first jig and the second jig; and a stopper detachably provided adjacent to an end of the second portion of the first jig.

Claims (20)

1. A method for manufacturing a display device, comprising:

coupling clamps to lateral ends of a display panel;

aligning the display panel and a cover window to face each other, the cover window including a planar portion and a curved portion that is provided in at least one side of the planar portion;

providing a stopper adjacent to an end of the curved portion of the cover window;

contacting the display panel and the planar portion of the cover window;

preventing the display panel from contacting ends of lateral sides of the cover window by the stopper when the clamps are separated from the display panel;

removing the stopper from between the display panel and the end of the curved portion of the cover window; and

contacting the display panel to the curved portion of the cover window.

2. The manufacturing method of the display device of claim 1 , further comprising bending the display panel toward the cover window before the display panel and the planar portion of the cover window contact each other.

3. The manufacturing method of the display device of claim 1 , wherein the display panel and the cover window contact each other from a center portion of the cover window.

4. The manufacturing method of the display device of claim 1 , wherein the aligning of the cover window and the display panel to face each other comprises:

receiving the cover window in a first jig that matches the shape of the cover window; and

locating the display panel on a second jig that faces the first jig.

5. The manufacturing method of the display device of claim 4 , wherein the contacting of the display panel and the planar portion of the cover window comprises:

moving the clamps close to the second jig; and

moving the second jig toward the first jig.

6. The manufacturing method of the display device of claim 5 , wherein the contacting of the display panel and the planar portion of the cover window further comprises moving the first jig to the second jig.

7. The manufacturing method of the display device of claim 6 , further comprising separating the clamps from the display panel after the display panel and the planar portion of the cover window contact each other.

8. The manufacturing method of the display device of claim 7 , wherein, when the clamps are separated from the display panel, the ends of the curved portion of the cover window and the display panel are prevented from contacting each other by the stopper.

9. The manufacturing method of the display device of claim 7 , further comprising bonding the display panel and the cover window by applying pressure thereto after the display panel and the curved portion of the cover window are bonded to each other.
