Abstract: The invention provides a linear organic electroluminescent light source which is high in brightness and capable of realizing white color. A brighter light source can be obtained compared with a light source having only one organic electroluminescent element by forming the organic electroluminescent element to have at least one organic layer, which emits light, on both sides of a transparent substrate, and covering the transparent substrate with a mirror which is high in reflectance except one end face of the transparent substrate. When the same brightness as that of a light source having one element is obtained, the power consumption can be suppressed. The light source can thus emit white light.

Abstract: The present invention provides an organic EL display device in which a transparent electrode pattern on the substrate is barely visible when no luminescence occurs in the organic EL elements. A transparent anode layer deposited on a transparent substrate is formed in a pattern which corresponds to a light emitting pattern. In the same plane with the anode layer within the display area, a dummy pattern is provided, such that it is electrically isolated from the anode layer. The dummy pattern is made of the same material and is formed with the same thickness as the anode layer. Thus, an interface between the transparent substrate, and a layer made of the anode layer material (the anode layer and the dummy pattern) is formed over the entire display area. When the organic EL elements are not light emitting, light reflection on the interface occurs uniformly over the entire display area.
