Disclosed is an organic electroluminescence element that can provide uniform light emission over the entire surface and also can reduce the risk of short circuit and leakage. An organic electroluminescence elementaccording to the present invention includes a substrate, a first electrode, a second electrode, an organic layerincluding a light-emitting layer, and an auxiliary wiring layer. The first electrode, the organic layer, and the second electrodeare laminated on one surface of the substratein this order. The organic layeris connected electrically to both the electrodes. The auxiliary wiring layeris arranged at a position where the auxiliary wiring layeris not in contact with the organic layer. The auxiliary wiring layeris connected electrically to the second electrodeand is not in contact with the first electrode

Provided is an image-capturing device that reduces the effect of direct incident light on an image-capturing element and allows a high contrast image to be obtained. An image-capturing device includes: an image-capturing element; a light emitting element; and an image data correction unit, wherein the light emitting element irradiates a subject with light, the image-capturing element senses the light reflected by the subject and generates an image data, and the image data correction unit corrects the image data by subtracting incident light directly entered into the image-capturing element from the light emitting element without being reflected by the subject from the image data.

A light emitting device comprises a light emitting element disposed within a space surrounded by a reflective surface of a reflector disposed on a board. A lower portion of the reflector is placed within a recess formed in the board, and a side wall of the recess is interposed between the lower end of the reflective surface of the reflector and the light emitting element.

Light emitting device

A surface light-emitting element radiates light emitted to a side of a surface light-emitting device. The surface light-emitting device includes: a polygonal transparent substrate, and a light-emitting element disposed on one face of the transparent substrate. The light-emitting element is a laminated body including a transparent electrode which is positively charged and functions as an anode, a negative electrode which becomes negatively charged and functions as a cathode opposite the transparent electrode, and a light-emitting layer between the transparent electrode and a negative electrode. Lengths of respective sides and a thickness of the transparent substrate have a relationship that if b denotes the thickness of transparent substrate, dividing the lengths of the respective sides by 4b results in values ranging from 0.5 (inclusive) to 10 (inclusive).

Surface light-emitting device

A translucent material substrate is shaped such that high luminous efficiency can be obtained in an organic EL light source in which light is emitted from a translucent material substrate to the atmosphere. The organic EL light source includes a luminescent layer composed of an organic luminescent element, a transparent electrode and a counter electrode, and a translucent material substrate. The translucent material substrate has a truncated quadrangular pyramidal shape having a surface in abutment with the luminescent layer as the bottom face of the shape. The bottom face is formed in the shape of a square in which the length of one side is 'b', and the top face opposite the bottom face is formed in the shape of a square in which the length of one side with respect to the same extending direction as that of the 'b'-length side is &#x201c;a&#x201d;. In addition, the shape of the translucent material substrate has thickness &#x201c;c&#x201d;. The translucent material substrate is shaped so that a ratio (a/b) of length a of a side of the top face to length b of a side of the bottom face in the same extending direction as that of the side is 0.3 or higher but not higher than 0.95, and that a ratio (b/c) of length b of a side of the bottom face to the thickness c of the translucent material substrate is 10 or lower.
