Abstract

【課題】　薄型で且つ光源から放たれた光を有効に利用することが可能な照光装置これを備えた入力装置を提供する。 【解決手段】　基板２に凹部２ａが形成され、この中に発光素子６が設けられた状態で封止材９によって封止されている。このような基板２の上に、透明な薄い樹脂フィルムで形成された導光層４が接着層３を介して固定することにより、照光装置１Ａの薄型化が可能となる。発光素子６で放たれた光は、封止材９および接着層３を介して導光層４に進入する。導光層４と接着層３との境界面および導光層４と空気層５との境界面で全反射した光が導光層４内を進行する。そして、このとき全反射しない一部の光が導光層４を形成する透明樹脂フィルムの表面から外部に漏れ出して照光装置１Ａの表面の全体が明るく照光される。
