Abstract

　駆動素子の閾値電圧のばらつきを補償する回路を正しく動作させ、補償動作によって他の画素回路の輝度が変動することを防止するために、画素回路１００を次のように構成する。電源配線Ｖｐと共通陰極Ｖｃｏｍとの間に駆動用ＴＦＴ１１０とスイッチ用ＴＦＴ１１５と有機ＥＬ素子１３０を設け、駆動用ＴＦＴ１１０のゲート端子とデータ線Ｓｊとの間にコンデンサ１２０とスイッチ用ＴＦＴ１１１を設ける。コンデンサ１２０とスイッチ用ＴＦＴ１１１の接続点Ｂと基準電源配線Ｖｒｅｆとの間にスイッチ用ＴＦＴ１１２を設け、駆動用ＴＦＴ１１０のゲート端子とドレイン端子との間にスイッチ用ＴＦＴ１１３を設け、駆動用ＴＦＴ１１０のゲート端子と接続点Ｂとの間にスイッチ用ＴＦＴ１１４を設ける。
