摘要： An organic electroluminescent device comprises an anode, a positive-hole transport layer made of an organic compound, an emitting layer made of an organic compound, and a cathode which are layered in sequence, further comprising an electron-injecting layer containing at least one of alkaline earth metal oxides and disposed between the emitting layer and the cathode. This device emits light at a high luminance and a high efficiency upon application of a low voltage together with reduction of the decrement of luminance in the running of emitting light of the device. Selection scope for cathode materials is expanded because of the device is free from the restriction of a low work function for the cathode layer. The cathode can be made a transparent electrode such as ITO. Anode and cathode lines may be formed with low resistance material. As a result, emitting efficiency and life time of the device is improved.

摘要： Disclosed is an organic electroluminescent display apparatus that has small panels each constituted by forming light-emitting sections, each comprising an organic electroluminescent layer, a transparent electrode and a metal electrode, on one major surface of the substrate. The transparent electrode has an extending portion formed to continuously extend from one major surface of the substrate to one side surface. The associated transparent electrodes of adjoining small panels are electrically connected via an anisotropic conductive sheet which has a conductivity only in the thickness direction. This design can narrow the non-light emitting area of each joint of the small panels.

摘要： An organic electroluminescent device comprises a cathode, an emitting layer of organic compound including a quinoline derivative, a positive-hole transport layer of organic compound and an anode which are laminated in sequence, further comprising a metal film having a work function equal to or lower than that of the anode and partially disposed between the anode and the positive-hole transport layer. This device achieves a high luminance efficiency per se. The existence of the metal film reduces resistance values of whole anodes. The entering efficiency of the positive-hole carrier is partially decreased due to the metal film line. This metal film line decreases the waste electric current that does not contribute the emission of the emitting layer.

摘要： In a self-emitting panel, self-emitting devices are arranged on a substrate in an array. Each self-emitting device includes a pair of electrodes and an emitting layer arranged between the electrodes. An insulating film insulates each of the self-emitting devices from others of the self-emitting devices on the substrate, by separating the emitting layer and at least one of the electrodes from those of the others. A sealing member is arranged to form a sealing region for shielding the self-emitting devices from the air, between the sealing member and the substrate. A sipe is provided at a portion beside an outermost self-emitting device arranged at an outermost part in the array such that the sipe is positioned closer to an edge of the substrate than the outermost self-emitting device is. The sipe has a depth in a direction of a thickness of the insulating film to divide the insulating film.

摘要： An organic electroluminescent display device includes organic electroluminescent films, each containing organic electroluminescent materials and sandwiched by a pair of electrodes, each forming a plurality of light-emitting elements above a substrate. Each pixel of the display device is composed of two different colors light-emitting elements, and the chromaticity of each color is controlled by changing the concentration of organic electroluminescent materials or by adding foreign materials thereto. For example, if the chromaticity of the red light-emitting element is set to a value shifted toward green side, various colors including white can be produced by mixing this red with blue of the blue light-emitting element. Then, the organic electroluminescent display device can produce high-quality quasi-color images by mixing two colors of which chromaticity values are properly controlled. By virtue of a two-color structure, the aperture ratio becomes high and the manufacturing process becomes simple.
