Polarizer, method of manufacturing the same, and flat panel display device including the polarizer
View Patent ↗A polarizer adapted to improve contrast and visibility of a display device, a method of manufacturing the polarizer, and a flat panel display device including the polarizer. In one embodiment, the polarizer includes a base and a plurality of grids disposed in a stripe pattern on the base. Here, the grids are separated from each other and formed of metal-containing graphite.
1. A polarizer comprising:
a base; and
a plurality of grids disposed in a stripe pattern on the base,
wherein the grids are separated from each other and comprise metal-doped graphite.
2. The polarizer of claim 1 , wherein the metal of the grids is selected from the group consisting of aluminum, silver, tungsten, gold, chromium, and combinations thereof.
3. The polarizer of claim 1 , further comprising a low-reflection layer disposed on a surface of each of the grids facing a direction in which external light is incident.
4. The polarizer of claim 3 , wherein the low-reflection layer has a thickness ranging from about 50 to about 1000 Å.
5. The polarizer of claim 3 , wherein the low-reflection layer comprises hydrogen, nitrogen, or combinations thereof.
6. A polarizer comprising:
a base; and
a plurality of grids disposed in a stripe pattern on the base,
wherein the grids are separated from each other and comprise metal-containing graphite,
wherein the metal-containing graphite contains from about 1 to about 10% by weight of metal.
7. The polarizer of claim 6 , wherein the metal of the grids is selected from the group consisting of aluminum, silver, tungsten, gold, chromium, and combinations thereof.
8. The polarizer of claim 6 , further comprising a low-reflection layer disposed on a surface of each of the grids facing a direction in which external light is incident.
9. The polarizer of claim 8 , wherein the low-reflection layer has a thickness ranging from about 50 to about 1000 Å.
10. The polarizer of claim 8 , wherein the low-reflection layer comprises hydrogen, nitrogen, or combinations thereof.
11. A polarizer comprising:
a base; and
a plurality of grids disposed in a stripe pattern on the base,
wherein the grids are separated from each other and comprise metal-doped graphite, and wherein the metal-doped graphite contains from about 1 to about 10% by weight of metal.
