A light emitting apparatus includes a translucent substrate, and a light emitting section and an optical filter section arranged in a first region of the substrate when viewed in a normal direction of a first surface of the substrate. The light emitting section has a laminate structure that includes, on the first surface of the substrate, a dielectric multilayer film, a first electrode, a functional layer with a light emitting layer, and a second electrode having semi-transmissive reflectivity. The optical filter section has a laminate structure that includes, on the first surface of the substrate, the dielectric multilayer film, the functional layer, and the second electrode. The dielectric multilayer film and the functional layer extend over the first region.

This application claims priority to Japanese Patent Application Nos. 2013-148276 filed on Jul. 17, 2013 and 2014-084339 filed on Apr. 16, 2014. The entire disclosures of Japanese Patent Application Nos. 2013-148276 and 2014-084339 are hereby incorporated herein by reference.
1. Technical Field
Several aspects of the present invention relate to a light emitting apparatus, a manufacturing method of a light emitting apparatus, a light receiving and emitting apparatus in which the light emitting apparatus is used as a lighting apparatus, and electronic equipment provided with the light receiving and emitting apparatus.
Referring now to the attached drawings which form a part of this original disclosure:
FIG. 1 is a block diagram showing a mechanical and electrical configuration of a biometric authentication apparatus;
FIG. 2A is a perspective view of a light receiving and emitting apparatus;
Hereinafter, the embodiments that specify the present invention will be described in reference to the drawings. The drawings are used to show portions that will be described in recognizable state by enlarging or contracting it appropriately.
First, a biometric authentication apparatus as an example of electronic equipment in which a light receiving and emitting apparatus provided with a light emitting apparatus of the present invention is applied will be described in reference to FIG. 1, FIG. 2A and FIG. 2B. FIG. 1 is a block diagram showing a mechanical and electrical configuration of a biometric authentication apparatus, and FIG. 2A is a perspective view of the light receiving and emitting apparatus, and FIG. 2B is a schematic cross-sectional diagram showing a configuration of the light receiving and emitting apparatus.
As shown in FIG. 1, a biometric authentication apparatus 100 as the electronic equipment of the present embodiment is an apparatus to perform identity authentication by taking a vein image of a finger F as a living body (subject), and is provided with a light receiving and emitting apparatus 150, a memory section 80, an output section 90, and a control section 70 that integrates and controls these sections.
