A sensing device includes a first electrode, a second electrode with a first opening portion, a light blocking layer with a second opening portion, an organic EL layer including a light emitting unit and being formed between the first electrode and the second electrode, and a light receiving unit. 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.
