  • Patent number: 11279653
    Abstract: An object is to enable sealing of a peripheral portion of a glass panel with less effort and time. A first metal introduction device 5A is moved from one first corner A at which two sides intersect each other of a pair of rectangular glass plates, toward another end of a first side Vab of the two sides, while performing filling with a metal material. Before the metal material filling the first corner A is solidified, a second metal introduction device 5B is moved from the first corner A toward another end of another second side Vad, while performing filling with a metal material. After the first side Vab and the second side Vad are filled with the metal material, both glass plates are rotated by 180 degrees, and the first metal introduction device 5A is moved toward another end of a fourth side Vcd of two sides intersecting each other at a second corner C diagonal to the first corner A, while performing filling with a metal material.

  • Patent number: 11276584
    Abstract: A method for producing a glass substrate according to the present invention includes the steps of: (I) forming a through hole (11) in a glass sheet (10); (II) forming a resin layer (20) on a first principal surface of the glass sheet (10) using a resin composition sensitive to light having a predetermined wavelength ?1; (III) photoexposing an area of the resin layer (20) that covers the through hole (11) by irradiating the area with light U having the wavelength ?1 and applied from the direction of a second principal surface of the glass sheet (10); and (IV) forming a through-resin hole (21) by removing the area photoexposed in the step (III). The glass sheet (10) protects the resin layer (20) from the light U so as to prevent the resin layer (20) from being photoexposed by beams of the light U that are incident on the second principal surface of the glass sheet (10) in the step (III).
