<P>PROBLEM TO BE SOLVED: To provide an antireflective transparent substrate which has a sufficient pencil hardness and suitable antireflective property. <P>SOLUTION: The antireflective transparent substrate in which, on one surface of the transparent substrate, an antireflective film 3 is stuck across an adhesive layer 2 and on the other surface, a transparent substrate and an antireflective film 5 are stuck one over the other across an adhesive layer 4; is characterized in that the difference (absolute value) in refractive index between the base material of the antireflective film 5 and the transparent substrate is ≤0.05 and the mean reflection factor of the antireflective films 3 and 5 at a wavelength of 450 to 650 nm is ≥0.1 % different. <P>COPYRIGHT: (C)2004,JPO |
