PROBLEM TO BE SOLVED: To provide a display device achieving satisfactory assembly working efficiency of a display unit and a casing.SOLUTION: The display device includes: a display unit 10 including an information display body 11, and a circuit board 12 disposed at a side opposite to a side of a viewer E of the information display body 11; an electronic component 12a mounted on the circuit board 12 and accompanying heat generation; and a casing 40 for storing the display unit 10. The casing 40 includes a wall part 44 having a cavity part 43 provided at a side opposite to the side of the viewer E of the circuit board 12. A heat transfer member 60 is interposed between the circuit board 12 and a heat radiation part 50 buried to the cavity part 43. The display unit 10 and the casing 40 are fixed by screws while penetrating both of a first through hole part 54 in which screws S are formed in the heat radiation part 50 and a second through hole part 61 formed in the heat transfer member 60, and a barrier part 45 for preventing interference between the heat transfer member 60 and the screws S is provided on the wall part 44 (casing 40).SELECTED DRAWING: Figure 4 【課題】 表示ユニットと筐体との組み付け作業性が良好な表示装置を提供する。【解決手段】 情報表示体１１と情報表示体１１の視認者Ｅ側とは反対側に配置される回路基板１２とを有する表示ユニット１０と、回路基板１２に搭載される発熱を伴う電子部品１２ａと、表示ユニット１０を収容する筐体４０とを備え、筐体４０は、回路基板１２の視認者Ｅ側とは反対側に設けられる空洞部４３を有する壁部４４を備え、回路基板１２と空洞部４３に埋設される放熱部５０との間には伝熱部材６０が介在しており、ネジＳが放熱部５０に形成された第１の貫通孔部５４、並びに伝熱部材６０に形成された第２の貫通孔部６１の双方を貫通した状態で、表示ユニット１０と筐体４０とはネジ固定され、壁部４４（筐体４０）には、伝熱部材６０とネジＳとの干渉を防止するための障壁部４５が設けられている。【選択図】図４
