Abstract
A laminated film includes, at least on one side thereof, a layer containing a hardening resin, having a total thickness of 1 to 100 μm, a light transmittance of 70% or more at a wavelength of 400 nm, a Young's modulus of 5 GPa or more when applying a nanoindenter to make a 1 μm depression in the thickness direction into the surface of the hardening layer, and undergoing a rate of deformation of 500 ppm or less after applying a stress of 0.5 MPa for 30 minutes.
