1. A sensor, comprising:
a light emitter including
a first electrode,
a second electrode, the second electrode being light-transmissive, and
a first light emitting layer provided between the first electrode and the second electrode; and
a light sensor including
a third electrode,
a fourth electrode, the fourth electrode being light-transmissive,
a fifth electrode provided between the third electrode and the fourth electrode, the fifth electrode being light-transmissive,
a first photoelectric conversion layer provided between the third electrode and the fifth electrode, and
a second photoelectric conversion layer provided between the fourth electrode and the fifth electrode, wherein
the first photoelectric conversion layer includes a third organic substance,
the second photoelectric conversion layer includes a fourth organic substance,
a wavelength of light absorbed by the third organic substance is different from a wavelength of light absorbed by the fourth organic substance, and
a difference between an absorption peak wavelength of the first photoelectric conversion layer and an absorption peak wavelength of the second photoelectric conversion layer is 50 nm or more.
