Abstract
【解決手段】本発明は、有機発光素子を含む画素領域と前記画素領域外側に形成される非画素領域とを含む第1基板と、前記第1基板の少なくとも画素領域上に合着される第2基板と、前記第1基板の非画素領域と前記第2基板との間に具備されて前記基板と前記封止基板を接着するフリットと、前記第1基板、前記第2基板、及び前記フリットの各外面の少なくとも一領域に形成される樹脂で構成される補強材を含んで構成される。
【選択図】図3
Description
しかし、フリットを使って密封する場合にも硝子材料のよく割れる特性によって、外部衝撃が印加される場合、フリットと基板の接着面に応力集中現象が発生し、これにより接着面からクラックが発生して基板全体に拡散されるという問題点が発生する。
有機発光素子は、本図面においてアクティブマトリックス方式で駆動されるように示されているので、これの構造を簡単に説明する。
150 フリット
160 補強材
200 封止基板
