Abstract
【解決手段】導光板(10)と、導光板の側面に配置された発光ダイオード(21)と、導光板の背面(11)に配置された反射シート(30)と、導光板の前面(13)に配置された、文字や図形等の標識(41)を含む表示を印刷された表示シート(40)と、これらを収容するケース(50)とを有する。発光ダイオードは導光板の内部に入り込ませて導光板の側面に配置され、ケースは透明な保護板(58)に覆われた開口(54)及び保護板に相対して配置された弾性樹脂塗布層(57)を有する中空体からなり、表示を開口から外部に露出させ、弾性樹脂塗布層によって保護板に圧接させて反射シート、導光板及び表示シートを収容している。
