Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid crystal panel production method which does not require masking processing following the etching processing, and which can suppress an affection of side etching to minimum level.SOLUTION: A liquid crystal panel production method comprises at least, a modification line formation step, a groove formation step, an etching step, and a cutting step. In the modification line formation step, a modification line which is formed along a shape cutting planned line corresponding to a shape of a liquid crystal panel to an array substrate and a color filter substrate, is provided, the modification line having a property in which the line is easily subjected to etching relative to other place. In the groove formation step, to the color filter substrate, a groove is formed along a terminal part cutting planned line for removing a region facing an electrode terminal part of the array substrate to the color filter substrate.SELECTED DRAWING: Figure 4 【課題】エッチング処理に伴うマスキング処理を不要にし、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液晶パネル製造方法を提供する。【解決手段】液晶パネル製造方法は、改質ライン形成ステップ、溝形成ステップ、エッチングステップ、および切断ステップを少なくとも含む。改質ライン形成ステップでは、アレイ基板およびカラーフィルタ基板に対して、液晶パネルの形状に対応する形状切断予定線に沿って形成される改質ラインであって、他の箇所よりもエッチングされ易い性質を有する改質ラインを形成する。溝形成ステップでは、カラーフィルタ基板に対して、このカラーフィルタ基板におけるアレイ基板の電極端子部に対向する領域を取り除くための端子部切断予定線に沿って溝を形成する。【選択図】図４
