Abstract

In an apparatus for manufacturing a display apparatus, the apparatus includes: a display panel comprising a display area, an adjacent area surrounding the display area, and a bending area extending from a side of the adjacent area, the display panel comprising a first material in the adjacent area and a second material in the bending area; a stage on which the display panel is located; and a curing device configured to concurrently cure the first material and the second material.

Claims (15)

1 . A method of manufacturing a display apparatus, the method comprising:

locating, on a stage, a display panel comprising a display area, an adjacent area surrounding the display area, and a bending area extending from a side of the adjacent area, such that the adjacent area is between the display panel and the bending area;

forming a dam in at least a part of the adjacent area and at least a part of the bending area;

applying a first material to the adjacent area;

applying a second material to the bending area; and

concurrently curing the first material and the second material.

2 . The method of claim 1 , wherein the dam comprises a same material as the second material.

3 . The method of claim 1 , wherein the applying of the first material to the adjacent area comprises covering a top surface of the display panel with the first material so that the top surface of the display panel in the adjacent area is not exposed.

4 . The method of claim 1 , wherein the first material and the second material are concurrently cured by one curing device.

5 . The method of claim 4 , wherein a wavelength band of light irradiated by the curing device is equal to or greater than 365 nm and equal to or less than 405 nm.

6 . The method of claim 5 , wherein an irradiation amount of light irradiated by the curing device is determined so that a curing rate of the first material in the adjacent area and the second material in the bending area at a deep portion and a surface is equal to or greater than 80%.

7 . The method of claim 1 , wherein the first material is cured by a first curing device and the second material is cured by a second curing device.

8 . The method of claim 7 , wherein the first curing device and the second curing device are spaced apart from each other in a first direction.

9 . The method of claim 7 , wherein a wavelength band of light irradiated by the first curing device and the second curing device is equal to or greater than 365 nm and equal to or less than 405 nm,

wherein an irradiation amount of light irradiated by the first curing device and the second curing device is determined so that a curing rate of the first material and the second material at a deep portion and a surface is equal to or greater than 80%.
