Optical filter device and electronic apparatus

摘要

An interference filter is fixed with respect to a base substrate by a fixing member which is disposed on one portion which is on the outer side of a filter region. Accordingly, since the periphery end of the interference filter, other than a portion (end portion) in which the fixing member is disposed, becomes a floated state (free end), it is possible to suppress the warping of the interference filter even when there is the difference in coefficients of thermal expansion with the base substrate. Further, spacer portions which are lower than the height of the fixing member are formed outside the filter region and on the portion separated from the fixing member. At the time of the impact, since the spacer portions come in contact with the base substrate to function as stoppers, it is possible to suppress occurrence of peeling-off or cracks on the fixing member.

主权项

1. An optical filter device comprising:
an interference filter which includes a first substrate, a second substrate which opposes the first substrate, a first reflection film which is provided on the first substrate, and a second reflection film which is provided on the second substrate and opposes the first reflection film with a predetermined gap interposed therebetween; and a housing which includes a base substrate for loading the interference filter and accommodates the interference filter, wherein the interference filter is fixed with respect to the base substrate by a fixing member which is disposed on one portion of the outside, in a plan view, of a filter region including the first reflection film and the second reflection film, spacer portions which are lower than a height of the fixing member are formed outside of the filter region and on portions separated from the fixing member, and the spacer portions are protrusions formed on the surface of the second substrate facing the base substrate.
