POLARIZER, METHOD OF MANUFACTURING THE SAME, AND DISPLAY DEVICE
First Claim
1. A polarizer comprising:
- a base layer comprising a first area and a second area enclosing the first area;
a polarizing part disposed on the first area of the base layer, the polarizing part comprising a plurality of linear patterns spaced apart from each other;
a dummy part disposed on the second area of the base layer and spaced apart from the polarizing part; and
a hard mask residue part disposed on a portion of the second area of the base layer between the polarizing part and the dummy part and contacting the base layer,wherein the polarizing part and the dummy part comprise;
a metal layer disposed on the base layer; and
a hard mask layer disposed on the metal layer and comprising the same material as the hard mask residue part.

Abstract
A polarizer including: a base layer including a first area and a second area enclosing the first area; a polarizing part disposed on the first area of the base layer and including a plurality of linear patterns spaced apart from each other; a dummy part disposed on the second area of the base layer and spaced apart from the polarizing part; and a hard mask residue part disposed on a portion of the second area of the base layer between the polarizing part and the dummy part and contacting the base layer. The polarizing part and the dummy part include a metal layer disposed on the base layer, and a hard mask layer disposed on the metal layer and comprising the same material as the hard mask residue part.

8. A method of manufacturing a polarizer, the method comprising:
-
preparing a base layer comprising a first area and a second area enclosing the first area; forming a metal layer on the first area and the second area of the base layer; etching the metal layer to form a first portion disposed on the first area and a second portion disposed on the second area and spaced apart from the first portion; forming a hard mask layer on the first portion, the second portion, and a third portion of the base layer between the first portion and the second portion; forming a resist layer on the hard mask layer; pressing the resist layer by a mold to form a resist pattern thereon; etching the hard mask layer by using the resist pattern as a first mask; and etching the first portion and the second portion by using the etched hard mask layer as a second mask. - View Dependent Claims (9, 10)

11. A display device comprising:
-
a first substrate comprising; a first base layer comprising a first area and a second area enclosing the first area; a first polarizing part disposed on the first area of the first base layer, the first polarizing part comprising a plurality of first linear patterns spaced apart from each other; a first dummy part disposed on the second area of the first base layer and spaced apart from the first polarizing part; and a first hard mask residue part disposed on a portion of the second area of the first base layer between the first polarizing part and the first dummy part and contacting the first base layer; a second substrate facing the first substrate; and a liquid crystal layer interposed between the first substrate and the second substrate, wherein the first polarizing part and the first dummy part comprise; a first metal layer disposed on the first base layer; and a first hard mask layer disposed on the first metal layer and comprising the same material as the first hard mask residue part. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
