Summary:PROBLEM TO BE SOLVED: To provide a thin flat glass substrate especially for display production, having the thickness of below 1.5 mm, the length of at least 1,800 mm, the width of at least 1800 mm, and a difference between the minimum thickness and the maximum thickness below 50 μm.SOLUTION: In a float glass processing treatment for producing a flat glass substrate having an improved quality, thickness fluctuation of a thin flat glass substrate formed by providing a flag 9 in a molten metal in a heat diffusion region on both surfaces of a glass sheet 3 under formation is suppressed minimally. 【課題】１．５ｍｍ未満の厚さ、少なくとも１８００ｍｍの長さ、少なくとも１８００ｍｍの幅をもち、及び最小厚と最大厚の差が５０μｍ未満である、特にディスプレイ製作用の薄平板ガラス基板を提供する。【解決手段】品質向上された平板ガラス基板製造のためのフロートガラス加工処理において、形成中のガラスシート３の両面上の熱拡散領域中の溶融金属中にフラグ９を設けて形成される薄平板ガラス基板における厚さ変動を最小減に抑える。【選択図】図２
