Claim Text:
1. 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 first compensating layer, a first polarizing layer and a first protecting layer sequentially on an outer surface of the first substrate, the first compensating layer including a first biaxial retardation film; a second polarizing plate including a second compensating layer, a second polarizing layer and a second protecting layer sequentially on an outer surface of the second substrate, the second compensating layer including a second biaxial retardation film; and a liquid crystal layer between the first and second substrates, wherein the first compensating layer includes a positive B-plate satisfying a relation of nz>nx>ny, wherein the second compensating layer includes a positive B-plate satisfying a relation of nz>nx>ny, nx, ny, and nz represents refractive indexes of each of the first and second compensating layers along the x, y, and z axes, respectively, wherein the x and y axes represents a plane direction of each of the first and second compensating layers, and wherein the z-axis represents a thickness direction of each of the first and second compensating layers.
