Abstract: A display device includes: an outer cover with light transmission properties; a design sheet with light transmission properties provided on the outer cover; a cushion layer with light transmission properties provided on a back surface side of the outer cover; and a light source provided on a back surface side of the cushion layer. When viewed in a cross section, the cushion layer includes: a plurality of first concave portions that are in a convex shape in a first orientation and a concave shape on a side opposite to the convex shape; and a plurality of second concave portions that are connected to the first concave portions and are in a convex shape in a second orientation and a concave shape on a side opposite to the convex shape. The first concave portions and the second concave portions are alternately provided.

Abstract: An input device includes a switch, light sources, and a light guide body. The switch is configured to switch between ON and OFF by being pressed. The light sources include a first light source and a second light source disposed at a position different from a position of the first light source. The light guide body guides a light emitted from the light sources in an opposite direction opposite from a pressing direction of the switch. The light guide body includes an output section, a first light guide leg section, and a second light guide leg section. The output section outputs the light emitted from the light sources in the opposite direction. The first light guide leg section is connected to the output section and guides the first light emitted by the first light source to the output section. The second light guide leg section is connected to the output section and guides the second light emitted by the second light source to output section. The output section includes a first design configured to emit light by reflecting the first light in the opposite direction and a second design configured to emit light by reflecting the second light in the opposite direction.

Abstract: A display device including (i) a light source and (ii) a light guide body which guides light emitted by the light source, and includes: a light guide leg that guides the light entering through a light entrance surface; and a light exit portion connected to the light guide leg and including a reflection design portion which reflects, in a first direction, a portion of the light guided by the light guide leg and another reflection design portion which reflects, in the first direction, another portion of the light. When viewed in the first direction, the reflection design portion is disposed in a first region on a second direction side with respect to a connecting portion of the light exit portion connected to the light guide leg, and the other reflection design portion is disposed in a second region on a third direction side with respect to the connecting portion.

Abstract: An input device includes: a panel on which a pressing operation is performed by an operating body; a substrate provided on a back surface side of the panel; a first electrode provided on the substrate; a holder that is provided on a back surface side of the substrate, includes a second electrode at a part facing the first electrode, and engages with the panel; a push-in detector that detects electrostatic capacity between the first electrode and the second electrode; and a vibration device held by the holder. The holder moves relative to the substrate when the pressing operation is performed on the panel, has rigidity and conductivity, and covers the second electrode from its back surface side.

Abstract: An input device includes: a switch to be switched by being pressed; a plurality of light sources including a first light source and a second light source; and a light guide that guides light emitted from each of the plurality of light sources. The light guide includes: an emission part that emits the light; a first light guide leg that is coupled to the emission part and guides first light to the emission part; and a second light guide leg that is coupled to the emission part and guides second light to the emission part. The emission part includes a first design that illuminates by reflecting the first light, and a second design that illuminates by reflecting the second light. The first light guide leg includes a first reflection surface that reflects the first light. The second light guide leg includes a second reflection surface that reflects the second light.
