Abstract
A glass plate includes a main surface, and a microscopic asperity surface disposed on the main surface, the microscopic asperity surface forming peaks and valleys. When a reference plane is defined as a plane at a center, in a direction of height, of an interval of highest frequency in a histogram of height of shape data of a square region having 2 μm per side in the microscopic asperity surface, the number of peaks that are higher than the reference plane by 20% or more of a maximum height difference in the square region is in a range between 1 or more and 300 or less.
Claims18
A glass plate comprising:
- a main surface;
- and
- a microscopic asperity surface disposed on the main surface, the microscopic asperity surface forming peaks and valleys, wherein
- when a reference plane is defined as a plane at a center, in a direction of height, of an interval of highest frequency in a histogram of height of shape data of a square region having 2 μm per side in the microscopic asperity surface,
- a number of peaks that are higher than the reference plane by 20% or more of a maximum height difference in the square region is in a range between 1 or more and 300 or less.
A glass plate comprising:
- a main surface;
- and
- a microscopic asperity surface disposed on the main surface, the microscopic asperity surface forming peaks and valleys, wherein
- summit density, obtained after removing a wavelength component of 0.05 μm or less from shape data of a square region having 2 μm per side in the microscopic asperity surface using an S-filter described in the International Standard ISO 16610-61, is in a range between 1/μm2 or more and 170/μm2 or less.
