摘要:
The present invention provides an organic electroluminescence element in which an anode layer 2, a light emitting unit 3, and a cathode layer 4 which each have optical permeability are stacked on a transparent substrate 1, the cathode layer 4 including a first charge generation layer 4a and a cathode 4c. The cathode 4c is formed by way of a facing target sputtering method. Even in the case where a cathode material which has optical permeability is used, the organic electroluminescence element is driven at a low applied voltage, has no angle dependability of an emission spectrum, and has high luminous efficiency.

There is provided a rotary compressor capable of preventing deterioration of performance following plug fixing carried out to prevent falling-off of a spring member. The rotary compressor comprises a cylinder constituting a rotary compression element, a roller engaged with an eccentric portion formed in a rotary shaft of an electric element, and eccentrically rotated in the cylinder, a vane abutted on the roller to divide an inside of the cylinder into a low pressure chamber side and a high pressure chamber side, a spring member for always pressing the vane to the roller side, a housing portion of the spring member, formed in the cylinder, and opened to the vane side and a hermetically sealed container side, a plug positioned in the hermetically sealed container side of the spring member, and inserted into the housing portion to fit into a gap, and an O ring attached around the plug to seal a part between the plug and the housing portion. In this case, a space between the cylinder and the hermetically sealed container is set smaller than a distance from the O ring to an end of the plug on the hermetically sealed container side.

A light-emitting body of the present invention includes an anode and a cathode at least partly facing the anode with the intermediary of a light-emitting material layer. An auxiliary electrode is formed, via an insulation layer, on the surface of the light-emitting body opposite to the surface where the anode faces the cathode via the light-emitting material layer. The cathode can be formed of a material that corrodes little. The light-emitting body therefore extends the life of a light-emitting device and therefore the life of a light-emitting display.

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.
