Abstract:
1. A sensing device comprising a light emitting unit, a light receiving unit, and a light blocking layer, 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 includes a light emitting layer that emits irradiation light that irradiates the subject, a first electrode that is positioned further to the subject side than the light emitting layer and that transmits the irradiation light and the reflected light, a second electrode that is positioned further to the light receiving unit side than the light emitting layer, blocks the irradiation light and the reflected light, and on which a first opening portion is formed, and an insulating layer that is positioned to correspond to the first opening portion, transmits the irradiation light and the reflected light, and partially insulates the first electrode and the second electrode, wherein the light receiving unit includes a light receiving element that receives the reflected light, the light blocking layer is provided at a position that corresponds to the first opening portion, blocks the irradiation light and the reflected light, and has a second opening portion formed thereon, and in a case when viewed in a plan view from the subject side, the light blocking layer overlaps the first opening portion and a light receiving face of the light receiving element is positioned within the second opening portion.
