Summary:To solve the problem that there is the risk that a defective pixel may not be rightly irradiated with a laser since a defect is hard to be recognized in an observation from a side which is not a light-emitting face, and because of difficulty of handling caused by no rigidity in a flexible top emission type organic EL panel.SOLUTION: Fixture to an observation table on which a panel is mounted is not cancelled between a defect confirmation time and a laser radiation time, and an optical system which observes a light-emitting state of pixels and an optical system which radiates a pulse laser beam are disposed oppositely.SELECTED DRAWING: Figure 5 【課題】フレキシブル型のトップエミッション型の有機ＥＬパネルにおいて、発光面ではない側からの観察においては欠陥の認識を行いにくいことと、剛性を有していないことによるハンドリングの困難さから、欠陥画素に正しくレーザが照射されない危険性がある。【解決手段】欠陥の確認時とレーザの照射時との間にパネルを搭載する観察台への固着を解除しない、および、画素の発光状態を観察する光学系と、パルスレーザ光を照射する光学系と対向させて配置する。【選択図】図５
