Patent ID: 8357437

Claim:
A light-shielding film-attached glass substrate comprising: a glass substrate; and a light-shielding film having a multilayer structure and being formed on the glass substrate, wherein said light-shielding film having a multilayer structure comprises: a first chromium oxynitride film (C r O x1 N y1 ); and a second chromium oxynitride film (C r O x2 N y2 ), each satisfying the following conditions and being laminated such that the first chromium oxynitride film is applied to the glass substrate and the second chromium oxynitride film is applied to the first chromium oxynitride film: 0.15 <x 1 <0.5, 0.1 <y 1 <0.35, 0.4 <x 1 +y 1 <0.65, 0.03 <x 2 <0.15, and 0.09 <y 2 <0.25; wherein a ratio I C /I G between a maximum intensity I G of X-ray diffraction at θ−2θ=42.0° to 45.0° of the glass substrate and a maximum intensity I C of X-ray diffraction at θ−20=42.0° to 45.0° of the light-shielding film-attached glass substrate satisfies I C /I G <1.5.
