摘要： PROBLEM TO BE SOLVED: To restrain generation and growth of dark spots, improve the conservation stability of an element and improve a lighting service life. SOLUTION: In this organic El element, a peripheral part between a board 2, on which the element is formed by laminating an organic layer including a luminescent layer between a pair of electrodes (a positive electrode and a negative electrode), and a sealing board 10 arranged facing opposite to the board 2 and spaced at a predetermined distance from the element is fixed and sealed in a dry atmosphere by a sealing film 9 formed of an organic adhesive. A recessed part 15 filled with the sealing film 9 is so formed in a region of the sealed part by the sealing film 9 on the surface side opposite to the element of the sealing board 10 to surround the element. The cross-linking density of the sealing film 9a filled in the recessed part 15 is slightly smaller than that of the sealing film 9b which abuts on the board 2 other than the recessed part 15, so that water molecules and the like passing through the sealing film 9 and intruding from the outside are caught.

摘要： PROBLEM TO BE SOLVED: To stabilize light emission by setting a range of a display segment as a flat surface. SOLUTION: On an insulating substrate 4 of glass or the like, straight wiring conductors 5a-5g are formed in parallel. On the substrate 4, a first insulation layer 6 having through holes 7 are formed in such a way that the wiring conductors 5a-5g are exposed at positions apart from display segments 2a-2g in the form of B. On the first insulation layer 6, a negative electrode 8 as a first electrode is formed to electrically connect the display segments common in both columns in a display pattern 3 to each other to reach the inside of the through holes 7. On the first insulation layer 6, a second insulation layer 9 having an opening part 10 opened in the form of the display segments 2a-2g to expose a flat surface of a negative electrode 8 is formed. On the second insulation layer 9, an organic layer 11 is formed, and on the organic layer 11, a positive electrode 12 as a second electrode is formed for each display pattern 3.

摘要： PROBLEM TO BE SOLVED: To provide a small and light weight print head having low power consumption suitable for full color indication. SOLUTION: Positive poles 3 in a direction parallel to a sub-scanning direction are arranged in a staggered fashion on a substrate in a main scanning direction. An organic layer including light emitting layers 4 (R, G, B) are formed on the positive poles 3. Negative poles parallel to the main scanning direction are provided on the organic layer by being intersected with the positive poles 3. The light emitting layers 4 in the respective intersections of the positive poles with negative poles are partitioned in dot shapes by opening sections of an insulation layer, respectively. The light emitting dots of each color of R, G, B are arranged in a staggered fashion in the main scanning direction. The negative poles 9 are scanned sequentially, then image signals of each of the colors are inputted to the positive poles in synchronism with the scanning and a head and a recording medium are relatively moved in synchronism therewith. The identical position on the recording medium is multiply exposed by dot lights of each of colors of R, G, B. A highly accurate full-color effect by virtue of the staggered fashion of the three color light emitting dots and an effect by the organic EL having reduced luminance variation lower than that of a fluorescent display tube generate a synergistic effect, then a high quality full color image is formed by only moving the head at once.

摘要： PROBLEM TO BE SOLVED: To obtain an org. electroluminescent element having a practically high luminance and a sufficient durability by incorporating a dithienylpyrrole deriv. into an org. luminescent layer which is sandwiched between a pair of electrodes of which at least one is transparent. SOLUTION: This element 1 comprises a glass substrate 2, a transparent ITO film anode 3, a hole transport layer 4, an org. luminescent layer 5, and a cathode 6. The org. luminescent layer 5 is a layer of a dithienylpyrrole deriv. represented by the formula (wherein R1 to R3 are each H, halogen, etc.) or is a layer of a mixture of tris(8-quinolinolato)aluminum (III) as a host material and the dithienylpyrrole deriv. as a guest material in a ratio of the guest material to the host material of 0.1-50mol%. Doping the org. luminescent layer with this material can improve the luminance and durability of the element, and the material can be used by itself as a luminescent material of the element.

摘要： PURPOSE:To enlarge a display area to a plane dimension seen from a display direction, by attaching a part of a side plate through a sealing material on a side plane part in the thickness direction of a substrate or the flat plate so that non-heating parts, in which display patterns can not be formed, are decreased. CONSTITUTION:At least a part of a side plate 29 is mounted through a sealing material 27 on a side plane part in the thickness direction of a substrate 21 or a flat plate 28. Therefore, because the side plane part of the substrate 21 or the flat plate 28 becomes a sealing part, only side plane part is allowed to be coated with the sealing material 27. Even without extra positions coated with the sealing material 27, air-tightness becomes fully reliable. Therefore, thickness of the side plates 29 can be made thin as long as strength is permitted, not requiring unnecessary coating of the sealing material 27. Thus, a non- luminous part l3, in which a display pattern of the anode or the like can not be formed, can be reduced. A display area of the fluorescent luminous tube to a plane dimension seen from the display direction can be enlarged.

摘要： PROBLEM TO BE SOLVED: To increase the rate of area of luminescent portions by decreasing intervals between organic EL elements. SOLUTION: This organic EL display device is made by arranging a plurality of organic EL elements 2. In the organic EL element 2, elements 7 each having an organic layer 6 including a luminescent layer sandwiched between a positive electrode 4 including wire 4a and negative electrodes 6 including wire 6a are formed as films on a substrate 3, and connection points P of the wires 4a, 6a are placed between luminescent parts 8 of the elements 7. A lid-shaped sealing member 9 is sealingly attached to a peripheral part of the substrate 3 to form a box-shaped enclosure 11 with a dry atmosphere kept in the interior. Terminals 13 each made up of a metallic pin are put through and fixed to through-holes 12 in the sealing member 9 so as to make contact with the wires 4a, 6a of the pair of electrodes 4, 6 at the connection points P.

摘要： PROBLEM TO BE SOLVED: To effectuate high image-quality exposure by emitting R, G and B lights from an equal point of light emission dots. SOLUTION: An organic EL element 23A for projecting a red light, an organic EL element 23B for projecting a blue light and an organic EL element 23C for projecting a green light are sequentially perpendicularly layered on a substrate 21. Light emission dots of the organic EL elements 23A, 23B and 23C are arranged in a serpentine form in a main scanning direction. Each of the organic EL elements 23A, 23B and 23C has an organic layer including a light emission layer 27 layered between an anode 24 and a cathode 28. Among light emission layers 27A, 27B and 27C, a light emission area of the layer of a lowest exposure efficiency is largest and is smaller as the exposure efficiency is higher. The layers are formed with center points registered.
