Abstract (en)
A plurality of LED light sources that are mounted on a front face of a mounting plate (1) are separated from each other respectively being disposed in cells (23) of a partitioning wall (2). Inner faces of the respective cells (23) are made of a material of low reflectivity. With respect to a normal line direction of the mounting plate (1), light of the LED light source is viewed, as light being brighter the closer to a back side and darker the closer to a near side on the inner face, in a state of being given gradations by the inner face.
