Abstract: PROBLEM TO BE SOLVED: To provide glass used for a panel for a flat panel display device which can be produced by a method other than the overflow downdraw process. SOLUTION: The glass panel for the flat panel display is produced by melting a batch for an aluminosilicate glass which is substantially free of alkali metal oxides and has a composition consisting essentially of, as calculated in percent by weight on an oxide basis, 60-67% SiO 2 , 16-23% Al 2 O 3 , 0-15% B 2 O 3 , 0-8% MgO, 0-18% CaO, 0-15% SrO and 0-21% BaO and 12-30% in total of BaO+CaO+SrO+MgO and drawing the melt into a thin sheet of molten glass by a float process.

Abstract: PROBLEM TO BE SOLVED: To provide a glass panel which is to be used for a flat panel display and can be prepared by a process other than an overflow down draw process.
SOLUTION: The glass panel comprises aluminosilicate glass. The aluminosilicate glass includes practically no alkali metal oxide and comprises essentially of, as calculated in percent by weight on an oxide basis, 49-58% of SiO
2 , 17.5-23% of Al
2 O
3 , 0-14.5% of B
2 O
3 , 0-8% of MgO, 0-9% of CaO, 0.4-13.5% of SrO and 0-21% of BaO, wherein the total of MgO+CaO+SrO+BaO is 13-28%; the strain point is higher than 640°C; the linear thermal expansion coefficient is in the range of 32-40×10
-7 /°C; and the weight loss after immersion in 5 wt.% aqueous hydrochloric acid at 95°C for 24 hours is less than 20 mg/cm
2 . The drawing of the glass plate is performed by the float process.
