Abstract: A display panel is attached to an appliance that includes first and second light sources, in which one of the first and second light sources is capable of being turned off when the other is turned on. The display panel basically includes a molded body, a front-side decorative layer, and a sheet-like member. The display panel is capable of individually illuminating a plurality of graphics, which is simultaneously molded and decorated, with light passing through a molded resin. In particular, a first graphic is illuminated in a first window by turning on the first light source, while a first back-side light-shielding region and a second front-side light-shielding region prevent a second graphic from being illuminated. The second graphic is illuminated in a second window by turning on the second light source, while a second back-side light-shielding region and a first front-side light-shielding region prevent the first graphic from being illuminated.

Abstract: A first groove is formed in a first main surface of a light guide member. A decorative layer is molded with the light guide member and provided on a second main surface of the light guide member. The decorative layer includes a first light-emitting portion that radiates the visible light emitted from a first light-emitting element from the light guide member and a second light-emitting portion that radiates the visible light emitted from the second light-emitting element from the light guide member. The first light absorbing member is disposed on a first groove bottom of the first groove, and has an absorptivity of visible light, which is higher than that of the light guide member. The first groove is positioned to block an optical path from the first light-emitting element toward a second region and an optical path from the second light-emitting element toward a first region.
