Zusammenfassung:A flat glass that can attain improvement to influence on visibility for use in FPD (Flat Panel Display) for liquid crystal, etc.; and a process for producing such a flat glass. There is provided a flat glass of 0.1 to 1.1 mm, especially 0.3 to 1.1 mm, sheet thickness containing bubbles of 100 to 1000 Vm major axis whose ratio of minor axis/major axis is 0.85 or greater. This glass sheet can be produced by conducting forming to a sheet thickness of over 1.0 to 1.5 times given sheet thickness (t) within 0.1 to 1.1 mm under a glass ribbon viscosity satisfying the relationship log Q
