<p>The present invention provides a sheet glass, a manufacturing method therefor, and a method and an apparatus for polishing an end edge portion of the sheet glass. The sheet glass is a rectangular glass board provided with an upper surface, a lower surface and two end faces between the two surfaces, at least one arris of the arris at the borders between the upper surface or the lower surface and the end faces or at least one end face are grinded by a grinding tape to form a fine processing face. The average surface roughness (Ra) of the fine processing face is below 20 nm, and the maximum valley depth (Rv) is below 200 nm.</p> |
