Abstract

A first hole of a predetermined depth is formed in a glass substrate by pressing a first drill against the lower surface of the glass substrate while rotating the first drill. A second hole is formed in the glass substrate by pressing a second drill against the upper surface of the glass substrate at the position facing the first hole while rotating the second drill. A through-hole is formed in the glass substrate by connecting the first hole with the second hole. Since the first and second holes are overlapped with each other in the thickness direction of the glass substrate, a step part formed on the inner peripheral part of the through hole is positioned on the upper surface side higher than the center of the glass substrate in the thickness direction.

Description

technical field

[0001] The present invention relates to a method for drilling a glass substrate and a glass substrate for a plasma display produced by the method; in particular, to a method for use in two pieces of glass to be assembled into a plasma display A glass substrate drilling method for making through holes for exhaust purposes in the rear side glass substrate in the substrate, and glass substrates for plasma displays. Background technique

[0002] By sealing two glass substrates with a sealant and filling the inside of the sealed glass substrates with a discharge gas, a plasma display (hereinafter, plasma display panel abbreviated as "PDP") as a light-emitting direct-view display is manufactured in an ultra-thin and large A display for a flat-screen TV that consists of a front glass substrate and a rear glass substrate. In the front glass substrate, a transparent dielectric and a MgO protective layer were formed over the display electrodes for discharge. In the r...
