Document Type and Number:
WIPO Patent Application WO/2024/004707
Kind Code:
A1
Abstract:
Provided is a film-attached glass substrate, which can achieve a high level of anti-glare and of scratch resistance. A film-attached glass substrate 1 comprises: a glass substrate 2; and an anti-glare film 3, which is provided on a main surface 2a of the glass substrate 2 and comprises silicon oxide as a primary component. The arithmetic mean height Sa of a surface 3a of the anti-glare film 3 is 0.3 µm or more. In a pencil hardness test specified in JIS K5600-5-4: 1999, when the presence or absence of scratches on the surface 3a of the anti-glare film 3 is assessed by observing the surface 3a of the anti-glare film 3 using a metal microscope at a magnification of 100 times, the pencil hardness is 7H or higher.
