Abstract
An acryl resin-containing film which is transparent and highly heat-resistant and has been significantly improved in brittleness is disclosed, satisfying the following equations (1) to (4), exhibiting a tension softening point of 105 to 145° C. and a photoelastic coefficient of −5.0×10to 8.0×10cm/N, while causing no ductile fracture. There is also disclosed a liquid crystal display which has achieved an improved yield in works of stamping a polarizing plate or sticking the plate to a panel and reduced color shift occurred depending on viewing angle.|(589)|≦10 nm  Equation (1)|(589)|≦20 nm  Equation (2)|(480)−(630)|≦5 nm  Equation (3)|(480)−(630)|≦10 nm  Equation (4) Numerical values of 589, 480 and 630 in parentheses represent the wavelength (nm) of a light used to measure an individual birefringence.
