Zusammenfassung:PROBLEM TO BE SOLVED: To provide a display light composed of a light emission body capable of obtaining substantial light emission from the surface and the end face, and a light source. SOLUTION: The display light 3 has a light emitting part of which a ratio of brightness of a light emission body 1 emitting light by the light from the light source fulfills a relation; 0.5≤L10/L210≤20, on condition that light beam transmission rete of the light emission body 1 at a length of light passage of 220 mm from a light source is not smaller than 0.1% and not larger than 80%, the brightness of the light emission body 1 at a position distant from the light source by 10 mm is L10, and the brightness of the light emission body 1 at a position distant from the light source by 210 mm is L210.
