Liquid crystal display and method of manufacturing polarizer plate
A liquid crystal display includes a liquid crystal panel, a first polarizer plate stacked on an upper surface of the liquid crystal panel, and a second polarizer plate stacked on a lower surface of the liquid crystal panel. The first polarizer plate may have an absorption axis inclination of +0.1 to +0.2 degrees, or the second polarizer plate may have an absorption axis inclination of −0.04 to less than 0 or greater than 0 to +0.1 degrees.

the second polarizer plate has an absorption axis inclination of −0.04 to less than 0 or greater than 0 to less than +0.1 degrees.
2. The liquid crystal display as claimed in claim 1 , wherein the first polarizer plate has an absorption axis inclination of greater than +0.1 to less than or equal to +0.2 degrees.
3. The liquid crystal display as claimed in claim 2 , wherein the second polarizer plate has an absorption axis inclination of −0.04 to less than 0 or greater than 0 to less than +0.1 degrees.
4. The liquid crystal display as claimed in claim 1 , wherein the second polarizer plate has an absorption axis inclination of −0.04 to less than 0 or greater than 0 to less than +0.1 degrees.
5. The liquid crystal display as claimed in claim 1 , wherein at least one of the first polarizer plate and the second polarizer plate includes:
a polarizer;
a first protective film stacked on an upper surface of the polarizer; and
a second protective film stacked on a lower surface of the polarizer.
6. The liquid crystal display as claimed in claim 5 , further comprising a compensation film stacked on a lower surface of the second protective film.
7. The liquid crystal display as claimed in claim 5 , wherein at least one of the first protective film and the second protective film is a tri-acetyl-cellulose film.
8. The liquid crystal display as claimed in claim 1 , wherein the liquid crystal panel includes an upper substrate, a lower substrate, and liquid crystals between the upper and lower substrates, the liquid crystals being vertical arrangement mode liquid crystals.
9. A method of manufacturing a polarizer plate, the method comprising:
preparing a polarizer;
attaching a protective film to at least one side of the polarizer to prepare a polarizer plate; and
cutting the polarizer plate at an inclined angle except for 0 or 90 degrees with respect to an absorption axis of the polarizer, wherein:
the inclined angle is in the range of −0.2 to less than −0.1 degrees with respect to the absorption axis, or
the inclined angle is in the range of greater than −0.1 to less than 0 or greater than 0 to less than or equal to +0.04 degrees with respect to a vertical direction to the absorption axis.
10. The method as claimed in claim 9 , wherein the inclined angle is in the range of −0.2 to less than −0.1 degrees with respect to the absorption axis.
11. The method as claimed in claim 9 , wherein the inclined angle is in the range of greater than −0.1 to less than 0 or greater than 0 to less than or equal to +0.04 degrees with respect to the vertical direction to the absorption axis.
12. The method as claimed in claim 9 , wherein the polarizer is prepared from a polyvinyl alcohol film.
13. The method as claimed in claim 12 , wherein preparing the polarizer includes stretching the polarizer in a stretching direction, and the absorption axis of the polarizer has the same direction as the stretching direction of the polarizer.
14. The method as claimed in claim 13 , wherein preparing the polarizer includes rinsing and swelling a polyvinyl alcohol film, dyeing the swollen polyvinyl alcohol film, stretching the dyed polyvinyl alcohol film in the stretching direction, and color-correcting the stretched polyvinyl alcohol film.
15. The liquid crystal display as claimed in claim 1 , wherein an absolute value of the absorption axis inclination of the second polarizer plate is greater than an absolute value of the absorption axis inclination of the first polarizer plate.
16. The liquid crystal display as claimed in claim 1 , wherein the second polarizer plate has an absorption axis inclination of −0.04 to less than 0 degrees, and an absolute value of the absorption axis inclination of the first polarizer plate is greater than an absolute value of the absorption axis inclination of the second polarizer plate.
