Optical device and electronic apparatus

An optical device comprising:

• a first substrate having a transmissive property, the first substrate having a first surface and a second surface outwardly opposite to each other along a first direction;
• a first wavelength variable interference filter including:
• a first reflective film, an entirety of the first reflective film being provided on the first surface of the first substrate;
• and
• a second reflective film, an entirety of the second reflective film being overlapped and aligned with the first reflective film along the first direction, a periphery area of the second reflective film being stacked on a periphery area of the first reflective film via either a first electrode or a second electrode, a center area of the second reflective film being located above a center area of the first reflective film via a first air gap along the first direction;
• and
• a second wavelength variable interference filter including:
• a third reflective film, an entirety of the third reflective film being provided on the second surface of the first substrate;
• and
• a fourth reflective film, an entirety of the fourth reflective film being overlapped and aligned with the third reflective film along the first direction, a periphery area of the fourth reflective films being stacked on a periphery area of the third reflective film via either a third electrode or a fourth electrode, a center area of the fourth reflective film being located below a center area of the third reflective film via a second air gap along the first direction.
