Abstract
Provided is a low reflection glass excellent in the abrasion resistance, the weather resistance, the productivity and the outer appearance, and a protective plate for a display. A low reflection glass includes a glass substrate and an antireflection film formed on the surface of the glass substrate. The antireflection film comprises an interlayer and an outermost layer in this order from the glass substrate side; and the outermost layer is a layer containing Si atoms, C atoms and O atoms. The content of C atoms is from 0.5 to 3 mol % based on 100 mol % of the total amount of Si atoms, C atoms and 0 atoms. The interlayer is a layer (a) (high refractive index layer) or a layer (b) (light absorbing layer). A protective plate for a display comprises a support substrate comprising the low reflection glass and a conductive film provided on a side on which no antireflection film is formed of the support substrate.
