PROBLEM TO BE SOLVED: To provide a lighting system of a vehicular instrument capable of changing a color of a display screen of a liquid crystal display panel despite a simple configuration.SOLUTION: The lighting system of a vehicular instrument includes: a liquid crystal display panel 31 for displaying an image of vehicle information; a plurality of light-emitting diodes 34 for lighting the liquid crystal display panel 31; and a light guide member 33 for guiding illumination light from the light-emitting diodes 34 provided on the back side of the liquid crystal display panel 31 to the liquid crystal display panel 31. Further, the lighting system includes a pair of a first light source group 34a and a second light source group 34b, the first light source group having a first light source 341 for emitting red light, a second light source 342 for emitting green light, and a third light source 343 for emitting blue light, and the second light source group similarly having fourth-sixth light sources 344-346. A first virtual line 34x formed by connecting the first light source 341 to the fourth light source 344, and a second virtual line 34y formed by connecting the third light source 323 to the sixth light source 346 are disposed so as to cross each other.
【課題】簡易な構成であっても液晶表示パネルの表示画面を色替えできる車両用計器の照明装置を提供する。【解決手段】車両情報を画像表示する液晶表示パネ31ルと、この液晶表示パネル31を照明するための複数の発光ダイオード34と、液晶表示パネル31の背面側に設けられる発光ダイオード34からの照明光を液晶表示パネル31に導く導光部材33と、を備え、赤色の照明を発する第1の光源341と、緑色の照明を発する第2の光源342と、青色の照明を発する第3の光源343とを有する第1の光源群34aと、同様に第4〜第6の光源344〜346を有する第2の光源群34bと、が一対設けられ、第1の光源341と第4の光源344とを結ぶ第1の仮想線34xと、第3の光源323と第6の光源346とを結ぶ第2の仮想線34yとが、交差するように配置される。【選択図】図5
