Abstract
The invention has an object to provide a display glass substrate capable of reducing poor film application and a method for manufacturing the same. The display glass substrate is a display glass substrate 20 for use in a flat panel display constituted of two main surfaces and four end faces. In this display glass substrate, when one main surface is set horizontal, the substrate end portion area 21 of at least one main surface existing in the range of 1˜30 mm inwardly of the substrate end E0 thereof has an elevation difference of 15 μm or less.
