Abstract
An electro-optical device includes: a light emitting element including a first electrode having reflectivity, a first light emitting layer configured to emit light in a first wavelength region including a first wavelength, a donor layer, an acceptor layer in contact with the donor layer, a second light emitting layer configured to emit light in a second wavelength region including a second wavelength, and a second electrode having reflectivity and transparency, stacked in order. The first wavelength region does not overlap the second wavelength region.
