Summary:To provide a display device which a user can see with both hands of the user unoccupied while lying down on the user's back and which can reduce glare the user is feeling.SOLUTION: A display device 100 is of a hanging type and includes: a display unit 110a having a plurality of pixels 111 and displaying an image corresponding to a picture signal; and a control unit 122 for controlling the display unit 110a. The control unit 122 controls the white peak luminance to be displayed in the display unit 110a in the white peak luminance adjustment range of which minimum value is 10% or lower of the highest luminance the display unit 110a can display. The display unit 122 controls the white peak luminance in two or more stages in the range equal to or less than 10% of the highest luminance.SELECTED DRAWING: Figure 1 【課題】ユーザが仰向けに横たわりながら、両手が自由な状態で閲覧でき、かつ、ユーザが感じるまぶしさを抑制できる表示装置を提供する。【解決手段】表示装置１００は、吊設型の表示装置１００であって、複数の画素１１１を有し、映像信号に対応する画像を表示する表示部１１０ａと、表示部１１０ａを制御する制御部１２２とを備え、制御部１２２は、表示部１１０ａにおいて表示する白ピーク輝度を白ピーク輝度調整範囲内で制御し、白ピーク輝度調整範囲の最小値は、表示部１１０ａが表示し得る最高輝度の１０％以下であり、制御部１２２は、白ピーク輝度を最高輝度の１０％以下の範囲において２段階以上の段階で制御する。【選択図】図１
