摘要： After entering a transparent substrate 9 of an organic EL device and passing through this substrate 9, an outside light L1 further passes through a transparent layer 10, a transparent electrode 12, and an organic light emitting layer 13 to be reflected by a reflective electrode 14. Herein, the reflective electrode 14 has irregularities and therefore the outside light L1 is diffused and reflected by this at various angles. These reflected lights are further diffused when passing through a boundary between the organic light emitting layer 13 and the transparent electrode 12 and through an irregularity surface 11 of the transparent layer 10, and outgo from the transparent substrate 9 toward a liquid crystal panel. On the other hand, lights L2 to L4 emitted from the organic light emitting layer 13 are diffused when passing through the boundary between the organic light emitting layer 13 and the transparent electrode 12 and through the irregularity surface 11 of the transparent layer 10, and outgo from the transparent substrate 9 toward the liquid crystal panel.

摘要： An organic EL element that is an electroluminescence element has at least an organic layer held between a pair of electrodes. At least an electrode made of material having a higher volume resistivity, of the pair of electrodes, is formed in a flat form. The organic layer is provided with a plurality of non-light emitting portions. The non-light emitting portions are provided so that a larger number of non-light emitting portions exist per unit area at a position physically closer to the position of a terminal portion at which the electrode made of material having the higher volume resistivity is connected to an external connection terminal. As a result, the level of current passing per unit area is substantially uniform at each position on the element.

摘要： An electroluminescence element includes a first electrode, a second electrode, and a light emission layer arranged between the first electrode and the second electrode. The first electrode is formed of a material having a higher volume resistivity than that of the material of the second electrode. A connector portion electrically connects a feeder portion to the first electrode. The resistance value of the connector portion differs in correspondence with a position at which the connector portion connects the feeder portion to the first electrode. The brightness distribution of the electroluminescence element is thus adjusted to a desired state.

摘要： A lighting device comprising a transparent substrate, an electroluminescent device and a light redirecting member. The transparent substrate has an incident surface, an end face and a light emitting surface opposite to the incident surface. The electroluminescent device is disposed on the incident surface and comprises a light emitting portion. The light redirecting member is disposed in a portion of the transparent substrate for redirecting light entering into the transparent substrate from the incident surface and which is transmitted toward at least one of said incident surface and said end face, to said light emitting surface. The incident surface and the light emitting surface each comprises a first area which overlaps said light emitting portion and a second area which does not overlap said light emitting portion. The portion of said transparent substrate is defined at least by the second areas of the incident surface and the light emitting surface.
