Abstract: Embodiments of the invention relate to a poly(meth)acrylimide film and a method for manufacturing such a film. At least one embodiment provides a poly(meth)acrylimide film that has (i) a total light transmittance of over 90% and (ii) haze of 2.0% or less. This film preferably has retardation of less than 50 nm. The method for manufacturing this film includes the following steps: (A) using a device provided with an extruder and a T die, a poly(meth)acrylimide molten film is continuously extruded from the T die; and (B) the poly(meth)acrylimide molten film is loaded by being fed between a rotating or circulating first mirrored-surface body and a rotating or circulating second mirrored-surface body, and then the film is pressed. During these steps, (C) the surface temperature of the first mirrored-surface body is in the range 100-200° C., and (D) the surface temperature of the second mirrored-surface body is in the range 20-200° C.
