Description
外部電源から前記有機発光素子に電圧を印加するステップと、
前記有機発光素子の白点(white−spot)領域、または黒点(dark−spot)領域を検出するか、前記有機発光素子に短絡欠陥が発生しない場合の作動温度より30%以上高い領域を検出する短絡欠陥が発生した導電性ユニットの検出ステップと、
前記短絡欠陥が発生した導電性ユニット内の短絡欠陥領域を検出するステップと、
前記短絡欠陥領域の第1電極および第2電極のうちの少なくとも1つの機能を喪失させて、短絡欠陥領域を修理するステップとを含む、有機発光素子の修理方法を提供する。
基板上に短絡防止層を形成した後、ITOを用いて複数の導電性ユニットを含む第1電極を形成し、補助電極としてアルミニウム(Al)を網形態に形成した。補助電極が露出した領域を感光性絶縁物質で絶縁し、発光層を含む有機物層および第2電極を順次に積層して、有機発光素子を製造した。
Claims (13)
