Sensing device and electronic apparatus

A sensing device comprising a first electrode, a second electrode in which a first opening portion is formed, a light blocking layer in which a second opening portion is formed, an organic EL layer that includes a light emitting unit and that is formed between the first electrode and the second electrode, and a light receiving unit, in which light from the light emitting unit is irradiated on a subject and reflected light from the subject is received by the light receiving unit, wherein

• the light emitting unit is a part of the organic EL layer that is wedged between the first electrode and the second electrode,
• the first electrode and the organic EL layer transmit the irradiated light and the reflected light,
• the second electrode and the light blocking layer block the irradiated light and the reflected light,
• the light blocking layer is positioned in the first electrode or between the first electrode and the second electrode, and in plan view from the subject side, the light blocking layer overlaps the first opening portion and the second opening portion is positioned within the first opening portion, and
• the light receiving unit is positioned further from the subject side than the second electrode, and in plan view from the subject side, the light receiving unit is positioned within the second opening portion.
