Abstract
【解決手段】導光板と(11)、導光板側面(14)に配列された複数の発光ダイオード(63)からなる発光源(61)と、導光板背面(13)に配置された反射材(41)と、導光板前面(12)に配置された表示材(21)とを有し、導光板背面または反射材反射面に反射ドットパターンを形成している。反射ドットパターンは、発光源の近傍に形成され、導光板周辺部から出射する光量を制御する第一の反射ドット領域(18)と、第一の反射ドット領域の内側に形成され、導光板の中心からの距離に対応して有効反射面積が減少するドットパターンを有し、導光板中央部から出射する光量を制御する第二の反射ドット領域(17)とを有する。
