<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device with a liquid crystal cell in which a contrast ratio in an oblique direction, a color shift amount in an oblique direction, and the feeling of a rough surface are improved. <P>SOLUTION: Regarding an IPS (in-plane switching) type liquid crystal display device where a pair of polarization plates each composed of a polarizer and two polarization plate protective films sandwiching the same are arranged on both the sides of a liquid crystal cell, in the polarization plate protective film on the cell side of the polarization plate arranged at the cell on the electrode side, Ro is 0 to 5 nm, Rt is -5 to 5 nm, and film thickness is 20 to 60 μm, and, in the polarization plate protective film on the cell side of the polarization plate arranged at the cell on the non-electrode side, Ro is 0 to 5 nm, Rt is 30 to 80 nm, and also, film thickness is 30 to 90 μm. <P>COPYRIGHT: (C)2008,JPO&INPIT |
