A flat glass panel 1 for a picture display device of the flat type, is formed by two glass cover plates (3, 5) with at least one glass plate (4, 4', 4", . . . ) between them, and a vitreous frit (8) between the cover plates along the outer edges of the cover plates so as to obtain a box-type glass panel in which a channel structure is present. After heating to the melting temperature of the frit (8), the panel is cooled down to a transitional temperature of the frit, while the space between the cover plates is partly exhausted during the cooling-down pha...
