To provide a light source which imparts high perceptibility to a user by making the user feel bright in a dark place, and emits light which hardly imparts a fatigue feeling to the user, an LED device and a light emitting display structure.SOLUTION: In a coordinate of the chromaticity of the CIE1931, light is included in a region whose color purity is 2 to 50 in a region surrounded by a line component WB and a line component WG for connecting a coordinate W (0.33, 0.33) indicating non-coloration, a coordinate B (0.091, 0.133) of 480 nm on a spectrum locus, and a coordinate G (0.373, 0.624) of 560 nm and the spectrum locus. A light source emits the light in which an area occupied by a spectral wavelength which continues in a wavelength region of 480 to 540 nm is not smaller than 15% with respect to a spectral wavelength area of 380 to 780 nm of the light source as a whole.SELECTED DRAWING: Figure 1

    【課題】暗所において明るく感じさせて高い視認性を与え、かつ疲労感を与えにくい光を発する光源、LED装置及び発光表示構造を提供する。【解決手段】CIE1931の色度図の座標において、無彩色を示す座標W(0.33,0.33)とスペクトル軌跡上の480nmの座標B(0.091,0.133)と、560nmの座標G(0.373,0.624)とを結ぶ線分WB及び線分WGとスペクトル軌跡に囲まれる領域における、色純度が2〜50の領域に含まれ、かつ、波長領域480〜540nmにおいて連続した分光波長が占める面積が380〜780nmの光源全体の分光波長面積に対して15%以上である光を発する光源を用いる。【選択図】 図1
