Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polarizing plate having excellent polarization characteristics with low transmittance in a normal direction, reducing light leakage in an oblique direction in the case of orthogonal Nicols arrangement and obtaining a liquid crystal display having excellent contrast or display quality.SOLUTION: A polarizing plate has transparent protective layers on one side or both sides of a polarizing film. The transparent protective layers satisfy inequalities y≤E in an arrangement function expressed by x≤15, E=64.448xin the case an in-plane phase difference value (nm) is represented by x and an angle (degree) between an optic axis of the polarizing film and a slow axis of the transparent protective layer is represented by y.
