LAMINATED POLARIZING PLATE SET AND IPS MODE LIQUID CRYSTAL DISPLAY DEVICE COMPRISING SAME

摘要

The present invention relates to a laminated polarizing plate set and to an IPS mode liquid crystal display device comprising same. More particularly, the present invention relates to a laminated polarizing plate set comprising positive A plates arranged on an upper polarizing plate and on a lower polarizing plate, wherein each positive A plate has a front surface phase difference value (R0) of 10 to 100 nm, and a refractive index ratio (NZ) of 0.9 to 1.1, and has a slow phase axis arranged parallel to the absorption axis of a polarizer. The present invention also relates to a liquid crystal display device comprising the laminated polarizing plate and to an IPS mode liquid crystal. The laminated polarizing plate set according to the present invention has superior physical resistance and maintains the designed phase difference compensating effects even when the plate set is exposed to a high-temperature, high-humidity environment over a long period of time, and therefore the IPS mode liquid crystal display device comprising the plate set can ensure a wide viewing angle even in a high-temperature, high-humidity environment, and improves chromatic vision at a surface thereof that is tilted.
