PROBLEM TO BE SOLVED: To decrease thickness of a device while achieving reception of reflected light from an object with high accuracy.SOLUTION: A sensing device is provided, which includes a light-emitting unit 20 positioned on an object F side of a light-receiving unit 30. The light-emitting unit 20 includes: a light-emitting layer 26 that emits irradiation light IL; a first electrode 22 that transmits the irradiation light IL and reflected light RL; a second electrode 24 that blocks the irradiation light IL and the reflected light RL, and has an opening formed therein; and an insulating layer 28 that is disposed at a position corresponding to the opening of the second electrode 24, blocks the irradiation light IL and the reflected light RL, and partially insulates between the first electrode 22 and the second electrode 24. The light-receiving unit 30 includes a light-receiving element D that receives the reflected light RL. A light-shielding layer BM is disposed at a position corresponding to the opening of the second electrode 24, blocks the irradiation light IL and the reflected light RL, and has an opening formed therein. In a plan view from the object F side, the light-shielding layer BM overlaps the opening of the second electrode 24 and the light-receiving face of the light-receiving element D is located within the opening of the light-shielding layer BM. |
