Mark substrate, window cover including mark and display device including the same

1. A mark substrate comprising:

a base substrate;

a light-blocking layer disposed on the base substrate, wherein an opening or a groove is defined in the light-blocking layer;

an infrared-transmitting member, wherein at least a portion of the infrared-transmitting member is disposed in the opening or the groove of the light-blocking layer to define a mark having a two-dimensional shape and optically distinguished from an adjacent area,

wherein a portion of the infrared-transmitting member contacts and covers an upper surface of the light-blocking layer.

2. The mark substrate of claim 1 , wherein the light-blocking layer includes a first light-blocking layer and a second light-blocking layer disposed directly on the first light-blocking layer.

3. The mark substrate of claim 2 , wherein a width of an opening of the first light-blocking layer is less than a width of an opening of the second light-blocking layer.

4. The mark substrate of claim 2 , wherein a width of an opening of the first light-blocking layer is greater than a width of an opening of the second light-blocking layer.

5. The mark substrate of claim 1 , wherein

an infrared ray transmittance of the infrared-transmitting member is about 80% or greater, and

a visible ray transmittance of the infrared-transmitting member is about 10% or less.

6. The mark substrate of claim 5 , wherein the infrared-transmitting member includes a coloring agent.

7. The mark substrate of claim 1 , wherein the mark has a shape of an alignment mark.

8. The mark substrate of claim 1 , wherein the mark is an identification mark including an information.

9. The mark substrate of claim 8 , wherein the identification mark is a QR code.

10. A window cover comprising:

a base substrate;

a light-blocking layer disposed on the base substrate and surrounding a transmitting area of the base substrate; and

an infrared-transmitting member, wherein at least a portion of the infrared-transmitting member is inserted into the light-blocking layer to define a mark having a two-dimensional shape and optically distinguished from an adjacent area,

wherein a portion of the infrared-transmitting member contacts and covers an upper surface of the light-blocking layer.

11. The window cover of claim 10 , wherein the light-blocking layer includes an opening or a groove, in which the at least a portion of the infrared-transmitting member is disposed.

12. The window cover of claim 10 , wherein the light-blocking layer includes a multi-layered structure.

13. The window cover of claim 10 , wherein

an infrared ray transmittance of the infrared-transmitting member is about 80% or greater, and

a visible ray transmittance of the infrared-transmitting member is about 10% or less.

14. The window cover of claim 10 , wherein the mark has a shape of an alignment mark.

15. The window cover of claim 10 , wherein the mark is a QR code.

16. A display device comprising:

a window cover including a light-blocking area and a transmitting area; and

a display panel combined with the window cover and overlapping the transmitting area,

wherein the window cover includes:

a base substrate;

a light-blocking layer disposed on the base substrate and overlapping the light-blocking area; and

an infrared-transmitting member, wherein at least a portion of the infrared-transmitting member is inserted into the light-blocking layer to define a mark having a two-dimensional shape and optically distinguished from an adjacent area,

wherein a portion of the infrared-transmitting member contacts and covers an upper surface of the light-blocking layer.

17. The display device of claim 16 , wherein the light-blocking layer includes an opening or a groove, in which the at least a portion of the infrared-transmitting member is disposed.

18. The display device of claim 16 , wherein the mark has a shape of an alignment mark.

19. The display device of claim 16 , wherein the mark is a QR code.
