Disclosed herein is a substrate for an electronic device. The substrate has a visually imperceptible surface texture that exhibits different coefficients of friction on various input objects. In some implementations, the texture of the textured substrate is created using a gas etching process.

Substrate having a visually imperceptible texture for providing variable coefficients of friction between objects

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 &#x3bc;m 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.

A glass sheet has one surface and the other surface facing the one surface in a thickness direction, wherein a fluorine concentration (average fluorine concentration by SIMS at a depth of 1 to 24 &#x3bc;m) in the one surface is higher than that in the other surface. The following expression is satisfied: 0.07&#x2266;&#x394;F/&#x394;HO. &#x394;F (mol %) is a value obtained by subtracting an average fluorine concentration in the surface having the lower fluorine concentration from that in the surface having the higher fluorine concentration, and &#x394;HO (mol %) is an absolute value of a value obtained by subtracting an average HO concentration in the surface having the higher fluorine concentration from that in the surface having the lower fluorine concentration.
