Abstract
An in-plane switching mode liquid crystal display device includes a first polarizing plate having a first compensating layer, a first polarizing layer and a first protecting layer on an outer surface of a first substrate, and a second polarizing plate having a second compensating layer, a second polarizing layer and a second protecting layer on an outer surface of a second substrate. The first compensating layer includes a positive B-plate where nz>nx>ny, and the second compensating layer includes a positive B-plate where nz>nx>ny, such that nx, ny, and nz represents refractive indexes 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 the first and second compensating layers, and the z-axis represents a thickness direction of the first and second compensating layers.
