Abstract

　表示エリア（１１）の外光の光量を検出する第１のフォトセンサ（ＰＳ１）と、遮光時の暗電流を検出する第２のフォトセンサ（ＰＳ２）と、第１のフォトセンサ（ＰＳ１）と第２のフォトセンサ（ＰＳ２）との選択を行う切り替えスイッチ（ＳＷ１、ＳＷ２）と、選択された第１のフォトセンサ（ＰＳ１）または第２のフォトセンサ（ＰＳ２）の出力と所定の基準値との比較を行うコンパレータ（１０２）と、第１のフォトセンサ（ＰＳ１）によるコンパレータ（１０２）の比較結果と、第２のフォトセンサ（ＰＳ２）によるコンパレータ（１０２）の比較結果との差分を演算し、この演算結果に応じて表示領域へ与える光量を制御する制御手段とを備え、表示装置に適用したフォトセンサにおける性能ばらつきによる検出誤差の影響を抑制して、表示領域へ与える光量を的確に調整する。
