Abstract
【解決手段】マザー素子基板100とマザー封止基板400が接着材シート30によって貼り付けられてマザーパネル200が形成されている。マザーパネル200から個々の有機EL表示パネル300を分離する際、分離線に沿って、レーザ106を照射し、この部分の接着材シート30の接着力を低下させておく。その後、分離線に沿ってスクライビング107を形成する。これによって、封止効果が低下せず、かつ外観がスムースが有機EL表示パネル300を実現することが出来る。
【選択図】図3
Description
レーザ照射によって接着材シートが変質し、炭化した部分は目視で判別することが出来る。また、印刷による接着材の場合も、炭化した部分の深さは、有機EL表示パネル300の端部から0.05mm以上である。この場合も、レーザが照射されない部分の接着材は通常の接着力を有しているので、レーザ照射したことによる有機EL表示パネル300の封止効果には影響が無い。
