A retardation-film integrated polarizing plate includes a polarizing plate stretched in a lengthwise direction thereof and having an absorption angle in the lengthwise direction, and a uniaxial retardation film having a slow axis in a widthwise direction thereof and an Nz coefficient of 0.9-1.1, in which the polarizing plate is laminated with the uniaxial retardation film so as to have the slow axis of the retardation film oriented at an angle of 90 degrees plus or minus 5 degrees to the absorption axis of the polarizing plate. The thus arranged polarizing plate is capable of enhancing the front contrast and the contrast at oblique viewing angles.
