Abstract: A glass substrate molding method includes: preparing a rotatable or wheelable molding die having a die surface and contacting the die surface with one of a pair of principal surfaces of a glass substrate made of a glass material containing an alkali metal oxide, the die having conductivity; keeping the one of principal surfaces contacted with the die surface at a temperature over 100° C. and equal to or lower than Tg+50° C.; applying direct-current voltage to the substrate to be higher voltage on the contacted one of principal surfaces than voltage on an opposite surface of the contacted one of principal surfaces; and rotating or wheeling the die and simultaneously moving the die or the substrate in a direction parallel to the contacted one of principal surfaces in conformity with rotation or wheeling speed of the die, to mold the contacted one of principal surfaces of the substrate.

Abstract: The present invention provides a cover glass for flat panel displays, which can simplify an edge treatment and is excellent in design, and a method for producing the same. The method includes: a local heating step S3 of locally heating regions 1b to be the bent portions 33 of the cover glass 30 in the sheet glass 1; and a bending step S4 of forming the skirt portions 32 by bending the sheet glass 1 at the regions 1b to be the bent portions 33, during or after the local heating step.
