摘要： PROBLEM TO BE SOLVED: To restrain the occurrence of a short circuit and leakage due to current-carrying to the possible minimum level, and to improve a yield by dry- etching a panel after forming a metallic electrode. SOLUTION: The edge parts 103a, 104a of a light emitting layer 103 and a metallic electrode 104 are formed thinner than the other part by dust/dirt 106 stuck on a transparent electrode 102 so that the tip of the edge part 103a of the light emitting layer is exposed without being covered with the metallic electrode 104. An ion generated by dry-etching enters from the arrow direction, and the light emitting layer 103 is removed from the edge part 103 side by reacting. At this time, because the edge part 104 of the metallic electrode is put in a projecting state but becomes more fragile than the other part of the metallic electrode 104 because of being thinned, the edge part 104a is disrupted/ removed by a collision of ions to thereby eliminate the thin part so far being an occurrence place of a short circuit and a leakage because both the edge part 103a of the light emitting layer and the edge part 104a of the metallic electrode.

摘要： PROBLEM TO BE SOLVED: To provide a pattern having various luminescent colors or pattern forms by evaporating and laminating a light emitting function layer on a desired positive electrode in the formation of the light emitting function layer of an element by evaporating an organic material on a substrate, and heating the other positive electrode. SOLUTION: A resist 2 patterned to a positive electrode is formed on the whole surface of one side of a transparent glass substrate 1. Positive electrodes 3a-3c corresponding to R, G, B are formed by etching. A prescribed current is carried to the positive electrodes 3b, 3c to heat them, and an organic material 4 is vacuum-evaporated on the positive electrode surface side of the base. In this case, since the positive electrodes 3b, 3c are heated to a prescribed temperature range, the organic material 4 is not evaporated on the positive electrodes 3b, 3c. After the heating is then stopped, and the positive electrodes 3a, 3c are heated to a temperature within a prescribed range by the current to evaporate an organic material 5, the temperature is returned to the original temperature, and the positive electrodes 3a, 3b are heated to a prescribed temperature range to evaporate an organic material 6. Then, negative electrodes 7a, 7c are evaporated in a prescribed area.

摘要： PROBLEM TO BE SOLVED: To keep a multilayer structure in an airtight state over a long period of time, by forming a sealing film, by a plasma CVD method using silane gas and nitrogen gas, on the multilayer structure comprising a positive electrode, a plurality of organic compound layers, and a negative electrode, provided on a glass substrate. SOLUTION: A positive electrode 2 comprising a transparent electrode of ITO etc., is formed by deposition on a transparent glass substrate 1, and on this, a hole injection layer 3 of copper phthalocyanine etc., a hole transfer layer 4 of a triphenylamine derivative etc., a luminous layer 5 of an aluminum chelate complex etc., an electron injection layer 6 of LiO2 etc., and a negative electrode 7 of Al etc., are deposited in this order, to form a multilayer structure 8. Then, a sealing film 9 made of SiNx is formed on the multilayer structure 8, and thus an airtightly sealed organic electroluminescent element is obtained. The sealing film 9 is formed by a plasma CVD method using a raw-material gas comprising only SiH4 gas and N2 gas. Because residual stresses are small in the plane directions, the sealing film causes no cracking or peeling, and stabilizes the luminescence of the element for a long period of time.

摘要： PROBLEM TO BE SOLVED: To evade a light emission defect caused by the occurrence of a leakage current by applying the voltage of the direction opposite to the voltage to be applied at the light emitting time to all light emitting elements during a prescribed period. SOLUTION: A cathode line 1 imparts successively ground potential to cathode lines B1 -Bn by scanning while successively switching switches 31 -3n to a ground terminal side at a fixed time interval. For instance, when the light emitting elements E2 ,1 , E3 ,1 are light emitted, since the switches 41 , 44 -4m are switched to the ground side, the light emitting elements E1 ,1 , E4 , 1-Em , 1 aren't light emitted. Further, by applying an opposite bias voltage Vcc of the same potential as a forward directional voltage applied when the light emitting element is light emitted to other cathode lines B2 -Bn excepting the cathode line B1 while scanning, the matter that a current from a current source flows through the other cathode lines B2 -Bn is prevented, and cross talk is prevented. Thus, the voltage of the direction opposite to the voltage applied at the light emitting time is applied.

摘要： PROBLEM TO BE SOLVED: To make the water content from the outside hard to intrude and make an organic film continuos without thinning the same to thereby improve the luminous characteristic by forming an insulation layer with an inclination so that it becomes thick toward the side of edge while thin toward a central part gradually. SOLUTION: A transparent film 109 of a luminous display element is formed in a gap between picture elements of a transparent electrodes 2. A material such as SiO having an insulative characteristic is used for the film 109, which is formed by a sputtering method or the like. To form the film 109, a photosensitive polyimide being an insulative photoresist is used, then it is uniformly adhered by a spin coating method or the like and thereafter it is removed except a specified gap part by patterning. An edge of the film 109 is formed such that a required exposed part is secured on a transparent electrode 2 while the thickness becomes thin gradually toward the edge so that the edge is not formed sharply. Accordingly, a protection layer functions effectively.
