Zusammenfassung:	To provide a method for manufacturing a glass panel with a transparent thin film and a method for manufacturing a liquid crystal panel with a transparent thin film which can minimize an influence of side etching accompanying etching processing.SOLUTION: The method for manufacturing a glass panel with a transparent thin film includes at least a laser scanning step and an etching step. In the laser scanning step, a laser is scanned through a transparent thin film along a shape cutting schedule line corresponding to the shape of a glass panel to be taken out to thereby form a modification line with such behavior as to be easily etched in multi-chamfering glass base material with a transparent thin film along the shape cutting schedule line. In the etching step, after the laser scanning step, the modification line is etched by bringing the multi-chamfering glass base material with a transparent thin film into contact with etching liquid while protecting the transparent thin film.SELECTED DRAWING: Figure 2 【課題】エッチング処理に伴うサイドエッチングの影響を最小限に抑制することが可能な透明性薄膜付ガラスパネル製造方法および透明性薄膜付液晶パネル製造方法を提供する。【解決手段】透明性薄膜付ガラスパネル製造方法は、レーザ走査ステップおよびエッチングステップを少なくとも含んでいる。レーザ走査ステップでは、取り出すべきガラスパネルの形状に対応する形状切断予定線に沿って透明性薄膜越しにレーザを走査することによって、形状切断予定線に沿って透明性薄膜付多面取り用ガラス母材にエッチングされ易い性質の改質ラインを形成する。エッチングステップでは、レーザ走査ステップ後に、透明性薄膜を保護しつつ透明性薄膜付多面取り用ガラス母材をエッチング液に接触させることによって改質ラインをエッチングする。【選択図】図２
