Patent abstract
A protective film for polarizing plates comprises an antireflection layer (reflectance≦0.5% at 550 nm) having high refractivity layers and low refractivity layers alternately laminated on a thermoplastic film (photoelastic coefficient≦9.0×10−12 Pa−1, saturated water absorption<0.05% by weight) and has 0.3 or smaller standard deviation of S, which is obtained by obtaining a reflectance R(λ) at a wavelength λ while λ is increased from 380 to 780 nm by an increment Δλ of 1 nm, calculating S:
