Photoelectric conversion device and manufacturing method thereof

A living body sensor for obtaining information in a living body, comprising:

• light-emitting elements respectively formed in some of a plurality of pixel regions on a substrate;
• light-receiving elements respectively formed in some of remaining pixels of the plurality of pixel regions;
• 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 living body sensor being configured
• to drive some light-emitting elements of the light-emitting elements at a first timing, to irradiate an interior of a living body with light from the driven light-emitting elements and to receive the light reflected from the interior of the living body by the light-receiving elements surrounding the driven light-emitting elements, and
• to drive the light-emitting elements other than the driven light-emitting elements at a second timing different from the first timing, to irradiate the interior of the living body with light from the other light-emitting elements and to receive the light reflected from the interior of the living body by the light-receiving elements surrounding the other light-emitting elements.
