PROBLEM TO BE SOLVED: To provide a production method for a glass sheet for display capable of producing a glass sheet for display having reduced dispersion of thermal shrinkage.SOLUTION: A production method for a glass sheet for display includes a heat treatment process for performing a heat treatment to a molded glass sheet. In the heat treatment process, heated gas is sent into gaps between a plurality of glass sheets arranged mutually at each interval, and the glass sheets are heated by heat arranged on the downstream side in the sending direction of the gas to the glass sheets.SELECTED DRAWING: Figure 2 【課題】熱収縮率のバラつきが低減されたディスプレイ用ガラス板を製造できるディスプレイ用ガラス板の製造方法を提供する。【解決手段】ディスプレイ用ガラス板の製造方法は、成形されたガラス板に対し熱処理を行う熱処理工程を備える。前記熱処理工程では、互いに間隔をあけて配置された複数の前記ガラス板の間の隙間に加熱された気体を送風し、かつ、前記ガラス板に対して前記気体が送風される方向の下流側に配置された熱によって前記ガラス板を加熱する。【選択図】図２
