Abstract
A light source device is provided which can output a plurality of lights by using a plurality of light transmitting media, and which can supply light of a sufficient intensity to the respective light transmitting media. An organic EL element, which is formed by successively layering a transparent electrode layer serving as an anode, an organic compound layer including a light-emitting layer, and a metal electrode layer serving as a cathode, is provided on the side surface of a fiber which propagates, in an axial direction, light from the organic EL element which has been introduced into an interior of the fiber. A plurality of the fibers are arranged in an array form and fixed by a conductive binder, and then sandwiched between two common electrode plates. Common voltage can be applied collectively to the organic EL elements of the plural fibers. Further, a transparent electrode exposed portion is provided at a light input side end portion of each fiber. An anode voltage can be applied independently to each of the organic EL elements of the plural fibers.
