PROBLEM TO BE SOLVED: To provide a lighting device capable of making a background of a substrate material look like a metallic tone even during night illumination.SOLUTION: A lighting device 1 comprises: a transparent substrate material 3 including a display unit 2 enabling transmitted illumination; and a light source 4 for illumination disposed on the rear surface side of the substrate material 3. The display unit 2 comprises: a translucent illumination unit 11 formed on the front surface side of the substrate material 3; a non-translucent edging unit 12 surrounding a periphery of the illumination unit 11; and a semi-translucent transmissive reflection layer 13 formed on the rear surface sides of the illumination unit 11 and the edging unit 12. The semi-translucent transmissive reflection layer 13 is formed on the rear side of the display unit 2. Furthermore, a non-translucent or semi-translucent metallic tone reflection layer 14 is formed on the rear surface side of the substrate material 3 excluding a light transmission unit 15 facing the illumination unit 11.

    【課題】夜間照明時においても基板材の背景が金属調に見えるようにする照明装置を提供する。【解決手段】透過照明が可能な表示部2を有する透明な基板材3と、この基板材3の裏面側に配設された照明用光源4と、を備えた照明装置1で、表示部2が、基板材3の手前面側に形成された透光性の照明部11と、この照明部11の周囲を取り囲む不透光性の縁取部12と、照明部11および縁取部12の裏面側に形成された半透光性の透過反射層13と、を有し、表示部2の裏側に半透光性の透過反射層13が形成され、更に、基板材3の裏面側に、不透光性または半透光性の金属調反射層14が、照明部11と対向する光透過部15を除いて形成される。【選択図】図2
