Polarizer, display panel including the same and method of manufacturing the same

A method of manufacturing a polarizer, the method comprising:

• forming a polymer layer and a metal layer, wherein the metal layer is formed on the polymer layer;
• and
• forming a plurality of linear metal patterns from the metal layer and a plurality of protrusions from the polymer layer, by pressing a bottom surface of a mold against the metal layer and the polymer layer, the bottom surface having a plurality of pressing patterns spaced apart from one another to form a groove between each pair of the pressing patterns,
• wherein at least a portion of each protrusion is inserted into a respective one of the linear metal patterns as a result of the pressing,
• wherein forming the polymer layer comprises:
• forming a first polymer layer on a substrate having a softening point equal to or less than about 50° C.;
• and
• forming a second polymer layer having a softening point equal to or more than about 100° C., on the first polymer layer, the second polymer layer contacting the metal layer,
• wherein the first polymer layer has a rubber phase at room temperature and the second polymer layer has a solid phase at room temperature.
