Abstract
A technology for remedying a defect in a glass substrate which constitutes a display panel. There is provided a method of remedying a defect in a glass substrate which constitutes a display panel, which method includes performing grinding of glass material, until reaching internal bubble (1b) from surface (1s) of glass substrate (1), with respect to a region where the internal bubble (1b) occurring within the glass substrate (1) is positioned and further also grinding off a glass material position surrounding the internal bubble (1b).
Claims3
A defect remedying method for remedying a defect in a glass substrate which constitutes a display panel, said method comprising:
- placing a defect remedying apparatus directly over a protrusion, serving as a surface defect, formed on the glass substrate, such that the defect remedying apparatus makes contact only with the protrusion, and
- carrying out a removal process with respect to the protrusion, in which removal process only a glass material forming the protrusion is removed from a surface of the glass material so that the protrusion is planarized.
