Abstract:
A hardcoat film includes: a substrate; and a hardcoat layer, in which the hardcoat film satisfies the following Formulas (i) and (ii), (i) E′(0.4)HC×dHC≥8,000 MPa·μm, (ii) E′(4)HC×dHC≤4,000 MPa·μm, E′(0.4)HC is an elastic modulus of the hardcoat layer obtained in a case where an elongation rate is 0.4%, E′(4)HC is an elastic modulus of the hardcoat layer obtained in a case where an elongation rate is 4%, and dHC is a film thickness of the hardcoat layer.
