Display device and manipulation switch equipped with it

A manipulation switch, comprising:

• a case;
• a manipulation button that is movably fixed to the case, the manipulation button having a display window;
• an illuminating body that is affixed to the manipulation button and illuminates the display window of the manipulation button;
• and
• a light source;
• wherein
• the illuminating body has a first illuminating member made of a resin having high light permeability, the first illuminating member being disposed close to the light source, and a second illuminating member made of a resin having low permeability, the second illuminating member being disposed close to the display window,
• a light guiding member is incorporated in the optical path between the light source and the illuminating body;
• and
• the first illuminating member and the second illuminating member are integrally formed together so that a first clearance is formed between the first illuminating member and the second illuminating member at least in an optical path extending from the light source, and a second clearance is formed between the light guiding member and the illuminating body so that when the manipulation button is pressed, the illuminating body does not abut the upper end of the light guiding member, and
• wherein the first illuminating member and the second illuminating member are formed in double molding and integrally connected to each other by legs integrally formed at position that is not on the optical path,
• an inclined surface or a curved surface that is used to diffuse light is formed on a surface of the first illuminating member in the optical path, the surface facing the second illuminating member, and
• an inclined surface or a curved surface that is used to condense light is formed on a surface of the second illuminating member in the optical path, the surface facing the first illuminating member.
