    • 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.
    • 本发明涉及一种层叠偏光板组件以及包括该组件的IPS模式液晶显示装置。 更具体地说,本发明涉及一种层压偏振片组,其包括布置在上偏振片和下偏振片上的正A片,其中每个正A片具有10至100nm的前表面相位差值(R0) ,和折射率比(NZ)为0.9至1.1,并具有平行于偏振器的吸收轴排列的慢相轴。 本发明还涉及一种包括层压偏振片和IPS模式液晶的液晶显示装置。 根据本发明的层压偏光板组具有优异的物理抵抗力,并且即使当板组长时间暴露于高温高湿环境时也维持所设计的相位差补偿效果,因此IPS 包括该板组的模式液晶显示装置即使在高温高湿环境下也可确保宽视角,并且改善倾斜表面处的彩色视觉。
