To provide a display device that can suppress a difference between temperature of a center part of a display area of a display panel and detection temperature of a temperature sensor to a small value.SOLUTION: A display device 20 comprises: a display panel 36 that has a display area 50 displaying an image on a front surface 36a and a peripheral area 52 which is arranged in an outside of the display area 50 and projects light incident on the rear surface 36b from the display area 50 as display light representing the image; a heat sink 32 that is arranged by facing the rear surface 36b of the display panel 36; a light transparent member 34 that is sandwiched between the display panel 36 and the heat sink 32; and a temperature sensor 38 that is arranged on the peripheral area 52 of the display panel 36, and detects temperature of the display panel 36. Seeing from a vertical direction for the front surface 36a of the display panel 36, the temperature sensor 38 is arranged at a position which does not overlap with at least one of the heat sink 32 and the light transparent member 34.SELECTED DRAWING: Figure 8

    【課題】表示パネルの表示領域の中央部の温度と温度センサの検出温度との差分を小さく抑えることができる表示装置を提供する。【解決手段】表示装置20は、前面36aに画像を表示する表示領域50及び表示領域50の外側に配置される周辺領域52を有し、背面36bに入射した光を、画像を表す表示光として表示領域50から投射する表示パネル36と、表示パネル36の背面36bに対向して配置されたヒートシンク32と、表示パネル36とヒートシンク32との間に挟持される透光部材34と、表示パネル36の周辺領域52に配置され、表示パネル36の温度を検出する温度センサ38とを備える。表示パネル36の前面36aに対して垂直な方向から見て、温度センサ38は、ヒートシンク32及び透光部材34の少なくとも一方と重ならない位置に配置されている。【選択図】図8
