Abstract

A cover window includes: a base film, and a coating layer positioned on the base film: and the coating layer includes a thermosetting coating layer and a photocurable coating layer. A display device includes: a display panel, and a cover window positioned on the display panel, and the cover window includes a base film, and a coating layer positioned on the base film, and the coating layer includes a thermosetting coating layer and a photocurable coating layer.

First claim

What is claimed is:

1 . A cover window comprising:
a base film; and a coating layer positioned on the base film, wherein the coating layer includes a thermosetting coating layer and a photocurable coating layer.

2 . The cover window of claim 1 , wherein:
the thermosetting coating layer is positioned on the base film, and the photocurable coating layer is positioned on the thermosetting coating layer.

3 . The cover window of claim 1 , wherein:
the photocurable coating layer includes two photocurable coating layers, and the thermosetting coating layer is positioned between the two photocurable coating layers.

4 . The cover window of claim 1 , wherein the photocurable coating layer includes at least one of an iodine-based initiator or a sulfuric acid-based initiator.

5 . The cover window of claim 4 , wherein:
the iodine-based initiator includes a compound represented by the following Chemical Formula 1, and the sulfuric acid-based initiator includes a compound represented by the following Chemical Formula 2:

6 . The cover window of claim 1 , wherein the thermosetting coating layer includes a boric acid-based initiator.

7 . The cover window of claim 8 , wherein the boric acid-based initiator includes a compound represented by the following Chemical Formula 3:

8 . The cover window of claim 1 , wherein a thickness of the coating layer is 100 μm or less.

9 . The cover window of claim i, wherein a thickness of the photocurable coating layer is 40% or less of a total thickness of the coating layer.

10 . A display device comprising:
a display panel; and a cover window positioned on the display panel, wherein the cover window comprises:
a base film; and
a coating layer positioned on the base film,
wherein the coating layer includes a thermosetting coating layer and a photocurable coating layer.

11 . The display device of claim 10 , wherein:
the thermosetting coating layer is positioned on the base film, and the photocurable coating layer is positioned on the thermosetting coating layer,

12 . The display device of claim 10 , wherein;
the photocurable coating layer includes two photocurable coating layers, and the thermosetting coating layer is positioned between the two photocurable coating layers.

13 . The display device of claim 10 , wherein the photocurable coating layer includes at least one of an iodine-based: initiator or a sulfuric acid-based initiator.

14 . The display device of claim 13 , wherein:
the iodine-based initiator includes a compound represented by the following Chemical Formula 1, and the sulfuric acid-based initiator includes a compound represented by the following Chemical Formula 2;

15 . The display device of claim 10 , wherein the thermosetting coating layer includes a boric acid-based initiator.

16 . The display device of claim 15 , wherein the boric acid-based initiator includes a compound represented by the following Chemical Formula 3:

17 . The display device of claim 10 , wherein a thickness of the coating layer is 100 μm or less.

18 . The display device of claim 10 , wherein a thickness of the photocurable coating layer is 40% or less of a total thickness of the coating layer.
