Optical device and housing

An optical device comprising:

• (a) a first substrate which is transparent to incident light;
• (b) a second substrate which is transparent to incident light and which opposes the first substrate;
• and
• (c) a frame member which connects the first substrate to the second substrate,
• wherein a lens chamber surrounded by the first substrate, the second substrate, and the frame member is filled with a first liquid and a second liquid which constitute a liquid lens,
• a region composed of an inorganic material and a region composed of an organic material coexist in the inner surface of the first substrate and the inner surface of the frame member facing the lens chamber, and
• a first insulating layer composed of an inorganic material, an adhesion layer composed of an organic material, and a second insulating layer composed of an organic material are stacked in that order on the inner surface of the first substrate and the inner surface of the frame member facing the lens chamber.
