Abstract

Disclosed is a method of patterning a conductive layer, a method of manufacturing a polarizer using the method and a polarizer manufactured using the same, and a display device having the polarizer. The method of patterning the conductive layer includes (a) patterning a resin layer to form grooves and protrusions, and (b) applying a conductive filling material on the resin layer so as to form a pattern using stereoscopic shapes of the grooves and the protrusions on the patterned resin layer.

Claims

1. A method of patterning a conductive layer comprising:

(a) patterning a resin layer to form grooves and protrusions; and

(b) applying a conductive filling material on the resin layer so as to form a pattern using stereoscopic shapes of the grooves and the protrusions on the patterned resin layer.

4. The method according to claim 1, wherein the conductive filling material is selectively applied on only the grooves, only the protrusions, or on a portion of the grooves and a portion of the protrusions of the resin layer in step (b).

5. The method according to claim 1, wherein step (b) is conducted using a selective wet or dry coating process.

6. The method according to claim 5, wherein the selective dry coating process of step (b) is an inclined sputtering process.

7. The method according to claim 1, wherein the resin layer is formed of an optically transparent organic material.

8. The method according to claim 1, wherein the resin layer is formed on a substrate that is formed of a material selected from the group consisting of an inorganic material and an organic material, and the resin layer is formed of a curable liquid resin.

9. The method according to claim 1, further comprising:

(c) forming a protective layer on the resin layer and the conductive layer after step (b).

10. The method according to claim 1, wherein the conductive filling material is selected from the group consisting of metal, a mixture of the metal and an organic material, and a conductive organic substance

11. A method of manufacturing a polarizer using the method according to claim 1.

14. A method of manufacturing a polarizer using the method according to claim 4.

15. A method of manufacturing a polarizer using the method according to claim 5.

16. A method of manufacturing a polarizer using the method according to claim 6.
