VEHICULAR DISPLAY DEVICE

To provide a vehicular display device which facilitates thickness reduction of the device.SOLUTION: A vehicular display device includes: a display panel 10; a circuit board 11; a processor 12 (a circuit element); a noise blocking plate 40; and a heat radiation member 50. The noise blocking plate 40 is disposed so as to cover the processor 12 from the back side of the display panel 10 when viewed in a visible direction, blocks electromagnetic noise, and is made of a metal. The heat radiation member 50 has a heat receiving surface 52, a first heat radiation surface 53, and a second heat radiation surface 54. The heat receiving surface 52 receives heat from the processor 12 through a first heat transmission material 12g. The first heat radiation surface 53 radiates heat to the noise blocking plate 40 through a second heat transmission material 40g. The second heat radiation surface 54 radiates heat into air. The heat radiation member 50 is made of a metal having heat conductivity higher than that of the noise blocking plate 40.SELECTED DRAWING: Figure 4 【課題】装置の薄型化促進を図った車両用表示装置を提供する。【解決手段】車両用表示装置は、表示パネル１０と、回路基板１１と、プロセッサ１２（回路素子）と、ノイズ遮断板４０と、放熱部材５０と、を備える。ノイズ遮断板４０は、プロセッサ１２を表示パネル１０の視認方向の奥側から覆うように配置されて電磁ノイズを遮断する金属製である。放熱部材５０は、受熱面５２、第１放熱面５３および第２放熱面５４を有する。受熱面５２は、第１伝熱材１２ｇを介してプロセッサ１２から受熱する。第１放熱面５３は、第２伝熱材４０ｇを介してノイズ遮断板４０へ放熱する。第２放熱面５４は気中放熱する。放熱部材５０は、ノイズ遮断板４０に比べて熱伝導率の高い金属製である。【選択図】図４
