Description
る発光装置であって、前記スイッチ素子は、前記発光ダイオード素子のオフ時に、前記発光ダイオード素子の順方向電圧以下の電圧を前記発光ダイオード素子に印加するpチャネル薄膜トランジスタであり、そのゲート電極にゲート電圧を制御するゲート電圧制御手段が接続されており、前記ゲート電圧制御手段は、前記発光ダイオード素子のアノード電圧(ただし、アノード電圧は電源電圧に等しい)をV1、前記順方向電圧をV2としたとき、前記オフ時に(V1−V2)以上でV1未満の前記ゲート電圧を前記ゲート電極に印加する構成である。
トの期間が長くなるという変動があったとしても、pチャネル薄膜トランジスタのゲート電圧を制御することによって、オーバーシュートの変動に対応してオーバーシュートを確実に抑えることができる。
