Abstract: An input device includes: a surface layer; a design sheet disposed on a front surface side or a back surface side of the surface layer; a cushion layer disposed on the back surface side of the surface layer and having a void therein; a plate-shaped frame disposed on a side of the cushion layer opposite to the surface layer; a main body that movably holds the frame in a first direction, in which the surface layer and the frame are stacked, when the surface layer is pressed; and a push-in detector mechanically connected to the frame. The design sheet includes a first portion in which a design is disposed and a second portion in which the design is not disposed in a plan view, and each of the surface layer and the cushion layer extends across the first portion and the second portion in the plan view.

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.
