Abstract
An optical device comprising first and second optical elements. The first optical element has: a first liquid crystal element; a first transmissive member formed on the first liquid crystal element and having a light incident surface on which external incident light is incident and a first light-outputting surface through which light reflected by the first liquid crystal element is outputted; and a second transmissive member having a second light-outputting surface through which transmitted light having been transmitted through the first liquid crystal element is outputted. The second optical element has: a second liquid crystal element; and a third transmissive member formed on the second liquid crystal element and joined to the first light-outputting surface.
