Abstract

An electro-optical device includes a transmission polarization axis conversion unit having a first surface and a second surface, an absorption polarization unit having transmission polarization axis in a first direction and having absorption polarization axis in a second direction, and a reflective polarization unit including a region having a transmission polarization axis in the first direction and a reflective polarization axis in the second direction, and an opening. The transmission polarization axis conversion unit can switch a first/second state, the first state is an incident light entering the first surface from the absorption polarization unit is converted into a first outgoing light of linearly polarized light in the second direction, and the first outgoing light is emitted from the second surface, the second state is the incident light converted into a second outgoing light of linearly polarized light in the first direction and emitted from the second surface.
