Abstract
An optical device is provided. The optical device includes a substrate and a plurality of filters. The plurality of filters are disposed over the substrate. Each of the filters includes a support body, a filter layer, and a centrosymmetric spacer. The support body has a first side surface and a second side surface opposite to the first side surface. The filter layer is on the first side surface. The spacer is attached to the first side surface by a second adhesive layer on the first side surface. The centrosymmetric spacer is attached to the filter layer, at least a peripheral portion of the filter layer is free from being covered by the centrosymmetric spacer.
