　バックキャビネット６０は、樹脂製とすることができ、図１に示すように、背面側内部の略中央に基板６４が取り付けられている。このように基板６４をバックキャビネット６０の内部に設けることで、背面側からの外観をスリム化することができる。また、予めバックキャビネット６０内に基板６４を配置しておくことで、基板を装着するためにバックキャビネット６０をひっくり返す必要もない。 The back cabinet 60 can be made of resin, and as shown in FIG. Thus, by providing the board | substrate 64 in the inside of the back cabinet 60, the external appearance from the back side can be slimmed. Further, by arranging the substrate 64 in the back cabinet 60 in advance, it is not necessary to turn the back cabinet 60 over to mount the substrate.
　また、バックキャビネット６０には、背面から前面側に向けて複数のリブ６１が突設されている。これらリブ６１は、後述するバックライト７０を取り付けるブリッジ７２が装着される。リブ６１を必要数よりも密に形成しておくことで、バックライト７０に応じてブリッジ７２の取付位置や設置個数の選択幅を広げることができる。 Also, the back cabinet 60 has a plurality of ribs 61 protruding from the back side to the front side. These ribs 61 are mounted with bridges 72 for attaching a backlight 70 to be described later. By forming the ribs 61 more densely than necessary, it is possible to widen the selection range of the mounting positions and the number of installed bridges 72 according to the backlight 70.
　バックキャビネット６０は、上面側が傾斜しており、複数の通気孔６２が形成されている。また、バックキャビネット６０の背面側下方にも複数の通気孔６３が形成されており、下側の通気孔６３からバックキャビネット６０の内部に外気が導入され、バックキャビネット６０の内部で放出される熱を奪って、温められた空気が上側の通気孔６２から排出される。 The back cabinet 60 is inclined on the upper surface side, and a plurality of vent holes 62 are formed. Also, a plurality of vent holes 63 are formed below the back side of the back cabinet 60, and outside air is introduced into the back cabinet 60 from the lower vent holes 63, and heat released inside the back cabinet 60. The heated air is discharged from the upper vent 62.
　さらに、バックキャビネット６０は、下面は、左右が背面に向けて膨らんだ形状であり、その中には図１に示すように夫々スピーカ１４が配置される。バックキャビネット６０は、スピーカ１４と対向する下面には、図３に示すように複数の音声出力孔６５が開設されている。 Furthermore, the lower surface of the back cabinet 60 has a shape in which the left and right sides swell toward the back surface, and the speaker 14 is disposed therein as shown in FIG.

　また、バックキャビネット６０の下面略中央には、スタンド１２を取り付けるための金属製の補強プレート６６が取り付けられている。 Further, a metal reinforcing plate 66 for attaching the stand 12 is attached to the lower cabinet approximately at the center of the back cabinet 60.
　バックキャビネット６０の前面側には、図１及び図３に示すように、バックライト７０が配置される。バックライト７０として、ＬＥＤ(発光ダイオード)７１を採用することができる。ＬＥＤ７１は、基板７１ａに実装され、基板６４と電気的に接続されて、発光が制御される。 As shown in FIGS. 1 and 3, a backlight 70 is disposed on the front side of the back cabinet 60. As the backlight 70, an LED (light emitting diode) 71 can be employed. The LED 71 is mounted on the substrate 71a and is electrically connected to the substrate 64 to control light emission.
　ＬＥＤ７１は、バックキャビネット６０の左右方向に懸架された複数のブリッジ７２に基板７１ａを介して所定間隔で配置することができる。ブリッジ７２は、前述のリブ６１にネジ止め８４される。ブリッジ７２は、金属製とし、長手方向に沿う側部を後方に向けて屈曲させている。背面に向けてコ字状断面とすることで、ＬＥＤ７１の放熱性とブリッジ７２自体の強度を可及的に高めることができる。 The LEDs 71 can be arranged at a predetermined interval on a plurality of bridges 72 suspended in the left-right direction of the back cabinet 60 via the substrate 71a. The bridge 72 is screwed 84 to the aforementioned rib 61. The bridge 72 is made of metal and is bent with a side portion along the longitudinal direction facing rearward. By making the U-shaped cross section toward the back, the heat dissipation of the LED 71 and the strength of the bridge 72 itself can be enhanced as much as possible.
　ＬＥＤ７１の照射光が効率よくパネルモジュール３０に照射されるように、図１に示す如く、バックキャビネット６０の前面側は、反射パネル７３にて覆われる。反射パネル７３は、前面側が光反射効率を高めるために白色となっており、ＬＥＤ７１が臨出する複数のＬＥＤ用孔７５が開設されている。反射パネル７３は、横方向の長さがバックキャビネット６０と略一致しており、縦方向の長さは、バックキャビネット６０にスピーカ１４等が配置される分だけ、バックキャビネット６０よりも短い。 As shown in FIG. 1, the front side of the back cabinet 60 is covered with a reflective panel 73 so that the light emitted from the LEDs 71 is efficiently applied to the panel module 30. The reflection panel 73 is white on the front side in order to increase the light reflection efficiency, and a plurality of LED holes 75 through which the LEDs 71 protrude are opened. The reflection panel 73 has a horizontal length substantially the same as that of the back cabinet 60, and the vertical length is shorter than the back cabinet 60 because the speaker 14 and the like are arranged in the back cabinet 60.
　反射パネル７３は、ＬＥＤ用孔７５からＬＥＤ７１が臨出するようにバックキャビネット６０に取り付けられる。 The reflective panel 73 is attached to the back cabinet 60 so that the LEDs 71 protrude from the LED holes 75.
　上記したフロントキャビネット５０、パネルユニット２０及びバックキャビネット６０の組立ては、まず、図１に示すように、バックキャビネット６０を上向きに配置した状態で、パネルユニット２０の液晶用基板３２のコネクタ３３を基板６４と電気的に接続し、パネルユニット２０をバックキャビネット６０に配置する。 As shown in FIG. 1, the assembly of the front cabinet 50, panel unit 20 and back cabinet 60 described above is performed by connecting the connector 33 of the liquid crystal substrate 32 of the panel unit 20 with the back cabinet 60 positioned upward. The panel unit 20 is arranged in the back cabinet 60.
　次に、フロントキャビネット５０を被せてバックキャビネット６０とネジ止め８２等することで液晶表示装置１０の組立てが完了する。なお、必要に応じて、バックキャビネット６０の下面にはスタンド１２をネジ止め８６することができる。 Next, the assembly of the liquid crystal display device 10 is completed by covering the front cabinet 50 and screwing it with the back cabinet 60 and the like 82. If necessary, the stand 12 can be screwed 86 to the lower surface of the back cabinet 60.
　図４は、説明のため、バックキャビネット６０を取り外した状態を示す斜視図である。また、図５も本発明の液晶表示装置１０の分解斜視図である。両図を参照することで、本発明の構成がより一層理解されるであろう。 FIG. 4 is a perspective view showing a state in which the back cabinet 60 is removed for explanation. FIG. 5 is also an exploded perspective view of the liquid crystal display device 10 of the present invention. The construction of the present invention will be better understood with reference to both the drawings.
　本発明によれば、パネルユニット２０の組立てのみをクリーンルームで行ない、その他の工程はクリーンルーム外で実施可能であるから、クリーンルームの使用効率を高めることができ、組立性を向上することができる。従って、特に大型の液晶表示装置１０への適用が好適である。 According to the present invention, only the assembly of the panel unit 20 is performed in the clean room, and other processes can be performed outside the clean room, so that the use efficiency of the clean room can be increased and the assemblability can be improved. Therefore, application to the large-sized liquid crystal display device 10 is particularly suitable.
　また、液晶パネル３１等がユニット化されているから、バックライト７０の交換等のメンテナンスの際に、パネルユニット２０は分解する必要がない。従って、メンテナンスは、クリーンルームに戻さなくて済み、設置場所で実施することができる利点がある。 Further, since the liquid crystal panel 31 and the like are unitized, the panel unit 20 does not need to be disassembled during maintenance such as replacement of the backlight 70. Accordingly, there is an advantage that the maintenance does not need to be returned to the clean room and can be performed at the installation location.
