Patent ID: 8743320

Claim:
An in-plane switching mode liquid crystal display device, comprising: first and second substrates facing and spaced apart from each other; a first polarizing plate including a supporting layer, a first polarizing layer and a first protecting layer sequentially on an outer surface of the first substrate; a second polarizing plate including a first compensating layer, a second compensating layer, a second polarizing layer and a second protecting layer sequentially on an outer surface of the second substrate, the first and second compensating layers including positive and negative biaxial retardation films, respectively, the first compensating layer comprising a positive B-plate satisfying a relation of nz>nx>ny, the second compensating layer comprising a negative B-plate satisfying a relation of nx>ny>nz, nx, ny, and nz representing refractive indexes of each of the first and second compensating layers along the x, y, and z axes, respectively, the x and y axes representing a plane direction of each of the first and second compensating layers, the z-axis representing a thickness direction of each of the first and second compensating layers; and a liquid crystal layer between the first and second substrates.
