Abstract: PROBLEM TO BE SOLVED: To improve durability of a device by providing an element for supporting an organic compound layer between a positive electrode layer and a negative electrode layer on a substrate and covering it with a protective film of tantalum oxide. SOLUTION: A positive electrode layer 2, a positive hole transport layer 4, an electron transport layer 5, a negative electrode layer 3, and a protective layer 6 are laminated in the order on a substrate 1. The protective layer 6 covers the luminous element and protects an upper surface of the luminous element, having this lamination structure from moisture and oxygen in the atmosphere. The substrate 1 is provided for forming a luminous element on its surface, for example, a plate, sheet, or film formed from transparent insulating material of glass, such as soda lime glass or the like or synthesized resin. A lower surface side of the luminous element is protected from moisture and oxygen in the atmosphere by the glass substrate 1. High level of shut off from moisture and oxygen is provided by forming the protective film 6 of a tantalum oxide film. The protective film 6 of amorphous makes it difficult for cracks to enter. The film 6 can have higher level of shut off, since it has a higher membrane packing rate.

Abstract: PROBLEM TO BE SOLVED: To provide a thin, small and inexpensive image sensor with an organic EL element light source. SOLUTION: In the image sensor, a solid-state image pickup element 10 to which the reflected light of an original 28 is imputed and the reading driving circuit 20 of the solid-state image pickup element 10 are formed on a substrate 1. A thin film organic EL element 30 having a thickness almost equal to the substrate 1 and irradiating the original 28 with line light emission is formed on a transparent substrate 21. The transparent substrate 21 of the thin film organic EL element 30 is fixed to the side of the substrate 1 on a solid-state image pickup element 10 so that the surfaces of both substrates become almost coplanar. Then, a transparent thin plate 32 is integrated on the solid-state image pickup element 10 and the transparent substrate 21 by transparent adhesive 27.

Abstract: PROBLEM TO BE SOLVED: To provide a high luminance element by imparting power in a specific range to an ITO film surface when the surface is modified by irradiating, on the ITO film, cations generated by an inert gas in a specific energy range. SOLUTION: In this surface treatment method, dirt in the surface region can be removed and a function (a charge injecting property) as an electrode of an organic light emitting element can be improved without causing the increase of the surface resistance of an ITO film by irradiating particles of which cation energy is 20-100 eV, desirably 30-60 eV with power of at least 10 mW/cm2 to 1 W/cm2 on the surface region within 5 nm in the depth direction of the ITO film. A surface treatment device is composed of a discharge lamp 2 composed by winding a high-frequency coil 3 around a quartz tube 4 in a chamber 1 and a substrate holder 6 to hold a substrate (ITO substrate) having the ITO film to be surface-treated. The holder 6 is connected to an ammeter 7 and a D.C. power source 8.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of the driving wirings of a printer head and the number of chips of a driving circuit by using a specific one-chip light emitting element array in stead on a conventional combining-type LED, and to dissolve the variation of light emitting characteristic. SOLUTION: A light emitting element array for yellow 200a, a light emitting element array for magenta 200b, the light emitting element array for cyanogen 200c and the light emitting element array for black 200d use one-chip light emitting element arrays arranged by covering the whole area of a main scanning distance D in a main scanning direction with respect to the rotation movement of photosensitive drums 1a to 1d. The one-chip light emitting element arrays use what are prepared from a single substrate and respectively cut-divided into four. The cost of the light emitting element array part of an image forming device is reduced to improve color reproducibility at a main scanning direction. In addition, as the light emitting characteristics of the respective single-chip light emitting element arrays are nearly equal, characteristic compensation between the respective element arrays is omitted.
