As shown in FIGS. 1 and 2, for example, the lamp connecting members 22 are held in every other fixing portion 42. It is conceivable to selectively attach the holding member 46 in the state and attach the input terminal 28 </ b> A of the fluorescent lamp 28 to the lamp holding portion 26 of the lamp connecting member 22. As a result, in the present embodiment, the brightness is about half that when the holding member 46 holding the lamp connecting member 22 is attached to all the fixing portions 42 of the frame 12.

さらに、図４、図６及び図７に示すように、このランプ接続部材２２の上部側の穴状電極部２２Ｂに隣り合った部分には、平面状に形成された平面電極部２２Ａが設けられている。この平面電極部２２Ａ上には、直方体状に形成され且つ弾性及び導電性を有したコネクタ材であるラバーコネクタ３２が、設置されている。尚、このラバーコネクタ３２内には複数本の金属線３２Ａが等間隔で入っていて、導電性を確保している。   Further, as shown in FIGS. 4, 6, and 7, a planar electrode portion 22A formed in a planar shape is provided in a portion adjacent to the hole-shaped electrode portion 22B on the upper side of the lamp connecting member 22. ing. A rubber connector 32, which is a connector material that is formed in a rectangular parallelepiped shape and has elasticity and conductivity, is installed on the planar electrode portion 22A. In the rubber connector 32, a plurality of metal wires 32A are inserted at equal intervals to ensure conductivity.

また、バックライトユニット１０の裏側であって図５における上面側となる反射板１４及びフレーム１２の部分には、先端側にテーパ状に突出した部分を有した爪部１８、２０が、直立するように複数並んで配置されている。一方、トランス３８だけでなく図示しない電子部品がプリント基板３６上に搭載されることで、バックライト駆動用のインバータユニットである電源ユニット３４が形成されており、図５に示すように、この電源ユニット３４は、プリント基板３６の下面側に配置された出力端子となるランドであるパターン面３６Ａから電力を外部に供給し得るようになっている。   Further, the claw portions 18 and 20 having portions protruding in a tapered shape on the front end side stand upright on the reflector 14 and the frame 12 on the back side of the backlight unit 10 and on the upper surface side in FIG. Are arranged side by side. On the other hand, not only the transformer 38 but also electronic components (not shown) are mounted on the printed circuit board 36 to form a power supply unit 34 that is an inverter unit for driving the backlight. As shown in FIG.
