Abstract

本発明の表示装置用照明装置は、並列配置された複数の管状光源１７と、前記管状光源１７の光出射側とは反対側に配設された光反射板１４と、を備え、前記光反射板１４には、隣接する前記管状光源１７の間に位置して、２つの傾斜面４１，４２を備える山型反射部４０が形成されており、前記山型反射部４０の２つの傾斜面４１，４２のうち前記管状光源１７の配列の内側に面する第１傾斜面４１について、第１山型反射部４０ａの当該第１傾斜面４１ａの傾斜角θ１が、前記第１山型反射部４０ａよりも前記管状光源１７の配列の内側に位置する第２山型反射部４０ｂの当該第１傾斜面４１ｂの傾斜角θ２よりも大きいことを特徴とする。
