A scuff plate has a first light guide element having a groove of predetermined shape formed in an underside of the element when viewed from below, a first light source that guides light to the first light guide element, light emission unit that is disposed below the first light guide element and that upwardly emits light differing in color from the first light source, and a half mirror layer interposed between the first light guide element and the light emission unit. Light from the first light source is guided to the first light guide element, and the guided light undergoes reflective diffusion at the groove (a character section). As a consequence, a desired character, or the like, is luminously displayed. In the meantime, light generated by the light emission unit exits through the first light guide element, whereupon an area (a background area) other than the groove (the character section) is illuminated in color that differs from the color of light from the first light source.
