Abstract
The thickness of a rear surface-side inorganic film () formed from the same material as that of each of front surface-side inorganic films (, and) and provided at a rear surface side of a resin substrate () having a heat resistance is set in a predetermined range with respect to the total thickness of the front surface-side inorganic films (, and) so that the curvature diameter calculated based on the linear elastic modulus, the coefficient of linear expansion, and the thickness of the resin substrate (); the linear elastic moduli, the coefficients of linear expansion, and the total thickness of the front surface-side inorganic films (, and); and the linear elastic modulus, the coefficient of linear expansion, and the thickness of the rear surface-side inorganic film () is 20 mm or more or −20 mm or less.
