| Zusammenfassung: | To provide a lighting device in which a receiving portion receiving a remote control signal from an operation remote controller is disposed on the opposite side to a light guiding plate across a reflection sheet, and which can prevent the generation of so-called black dot defects of an opening portion of the reflection sheet when the opening portion for receiving is formed on the reflection sheet.SOLUTION: One end in a longitudinal direction is located near an opening portion 4a of a reflection sheet 2. At an end portion on an opening portion 40a side of a transmission member 30 disposed while the other end in the longitudinal direction faces the receiving portion, a flange member 40 larger than an end portion area and the opening portion of the transmission member is provided, and the flange member 40 is disposed while blocking the opening portion 4a. The flange member 40 is formed in the same color or a similar color to the reflection sheet 4.SELECTED DRAWING: Figure 4
【課題】反射シートを挟んで導光板と反対側に、操作用リモコンからのリモコン信号を受信する受信部が配置されるとともに、反射シートに受信用の開口部が形成された場合に、反射シートの開口部が黒く見えるいわゆる黒抜けの発生を防止できる照明装置を提供する。【解決手段】長さ方向の一端が反射シート２の開口部４ａの近傍に位置し、長さ方向の他端が受信部に臨む状態で配置された伝送部材３０の開口部４０ａ側の端部に、伝送部材の端部面積及び開口部よりも大きいフランジ部材４０が設けられ、このフランジ部材４０は開口部４ａを閉塞した状態で配置されている。フランジ部材４０は、反射シート４と同色ないし近似色で形成されている。【選択図】図４ |
