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.COPYRIGHT: (C)2015,JPO&INPIT【課題】対象物からの反射光を精度よく受光できるようにしつつ装置を薄型化する。【解決手段】センシング装置において発光部20は受光部30より対象物F側に位置する。発光部20は、照射光ILを発する発光層26と、照射光ILと反射光RLを透過する第1電極22と、照射光ILと反射光RLを遮光すると共に開口部が形成された第2電極24と、第2電極24の開口部に対応する位置に設けられ、照射光ILと反射光RLを遮光すると共に第1電極22と第2電極24とを部分的に絶縁する絶縁層28とを備える。受光部30は反射光RLを受光する受光素子Dを備える。遮光層BMは、第2電極24の開口部に対応する位置に設けられ、照射光ILと反射光RLを遮光すると共に開口部が形成されている。対象物F側から平面視した場合に、遮光層BMは第2電極24の開口部と重なり、受光素子Dの受光面は遮光層BMの開口部内に位置する。【選択図】図2
