<P>PROBLEM TO BE SOLVED: To provide an IPS (In Plane Switching) type liquid crystal display wherein not only display quality but also a visual field angle are greatly improved by a simple construction. <P>SOLUTION: In the liquid crystal display comprising a first polarizing film, a first phase difference region, a second phase difference region and a liquid crystal cell wherein a liquid crystal layer is interposed between a pair of substrates, retardation Re in the first phase difference region defined by Re=(nx-ny)×d is 20 to 150 nm and the value Nz in the first phase difference region defined by Nz=(nx-nz)/(nx-ny) is 1.5 to 7 using in-plane refractive indices nx and ny (nx>ny), the refractive index nz in the thickness direction and the thickness d of the film, in-plane refractive indices nx and ny in the second phase difference region are substantially equal to each other, nx<nz is satisfied and retardation Rth in the thickness direction in the second phase difference region defined by Rth=ä(nx+ny)/2-nz}×d is -80 to -400 nm, and the transmission axis of the first polarizing film is parallel to the delay phase axis direction of liquid crystal molecules when black display is performed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
