1. A sensor comprising:
light-emitting elements respectively formed in some of a plurality of pixel regions on a substrate, the light-emitting elements irradiating an interior of a living body with light; light-receiving elements respectively formed in some of remaining pixels of the plurality of pixel regions, the light-receiving elements each comprising:
a sensor light-receiving element receiving the light emitted from the light-emitting element and reflected from the interior of the living body; anda monitor light-receiving element directly measuring some of the light emitted from the light-emitting element without emerging the light outside the substrate; a light-emitting element active matrix layer for driving the light-emitting element, formed on the substrate and including a thin-film transistor and an interconnection; and a light-receiving element active matrix layer for driving the light-receiving element, formed on the substrate and including a thin-film transistor and an interconnection, the sensor being configured
to receive the light reflected from the interior of the living body and obtained when some first light-emitting elements of the light-emitting elements are driven at a first timing by the sensor light-receiving elements surrounding the driven light-emitting elements, andto receive the light reflected from the interior of the living body and obtained when second light-emitting elements other than the driven first light-emitting elements are driven at a second timing different from the first timing by the sensor light-receiving elements surrounding the second light-emitting elements.
