An organic electroluminescent device includes at least an anode 2, a charge generating layer 3, a luminescent layer 4 and a cathode 5 in this order. The charge generating layer 3 has an area 3a containing an electron transporting material at the anode side, and an area 3b containing a hole transporting material and a material capable of forming a charge transfer complex with the hole transporting material by an oxidation-reduction reaction at the cathode side, the hole transporting material and the material being laminated or mixed. The hole transporting material is in a radical cation state.

Abstract: An organic EL light emitting device, in which a plurality of divided light emitting segments are connected in series, is efficiently manufactured without separate coating of organic EL light emitting layers with the use of a vapor-deposition mask. Conductor parts 5 are respectively formed on first electrodes 2b and 2c in boundary parts of adjacent light emitting segments a, b and c. Organic light emitting layers 3a to 3c and second electrode 4a to 4c are respectively stacked on each of the first electrode 2a to 2c. The conductor part 5 has a function for electrically connecting the first electrodes and the second electrodes in the adjacent light emitting segments, whereby the light emitting segments are connected in series.

Abstract: An illumination device is provided that has a superior decorative effect achieving a favorable dramatic effect and atmosphere. Sub-panels 2, 3, 4, 5 having the same shape as a main panel 1 are mounted pivotally to each side of the rectangular main panel 1 via hinges 6. Surface-emitting parts 1a, 2a, 3a, 4a, 5a formed of organic EL elements are mounted on the main panel 1 and each of the sub-panels 2, 3, 4, 5. By changing a set angle between the main panel 1 and each of the sub-panels 2, 3, 4, 5 and by independently controlling the lighting of each surface-emitting part 1a to 5a, a favorable dramatic effect and atmosphere can be created.

In an organic EL device having an organic layer, including an organic luminescent material, formed between a pair of counter electrodes, ultraviolet ray is irradiated to the organic layer, and the amount of irradiation is changed to form an emission pattern having a contrast caused by a luminous brightness corresponding to the amount of the irradiation of the ultraviolet ray.

Abstract: An evaporation source having a nozzle structure that makes the distribution of film thickness uniform in the width direction of a substrate and a vacuum evaporator using the same are provided. A vapor produced by evaporation or sublimation by heating to evaporation material is discharged from a long nozzle opening like a band. A deposited substrate is transferred in a direction perpendicular to the longitudinal direction of the nozzle opening while facing the nozzle opening. A discharge flow rate of vapor per unit area in the longitudinal direction of the nozzle opening is made to be maximum in a portion at a nozzle width direction position corresponding to a substrate edge position rather than a central part of the nozzle opening and a plurality of partition plates providing directivity to the flow of vapor are arranged inside the nozzle opening.
