摘要:
In a light-emitting device comprising an organic electroluminescent device including one or more organic thin layers (at least including a light-emitting layer) which are sandwiched between a transparent first electrode formed on a light-transmitting substrate and a second electrode, the light-transmitting substrate is formed so as to include parts for reflecting light emitted by the organic electroluminescent device (corresponding to a pixel) and thereby preventing the light from entering adjacent pixel areas. The light-transmitting substrate is formed of material having a refractive index of 1.65 or more or a refractive index higher than that of the light-emitting layer. A surface of the light-transmitting substrate opposite to the first electrode is provided with a light-diffusing function for avoiding total reflection. By such composition, a light-emitting device with no light leakage and excellent light extraction efficiency can be realized and thereby a high-intensity low-voltage-driven display device can be realized.

Refrigerant compressed by a first stage compression elements (30) run by a motor (20) is discharged in the closed container (10) via a silencer chamber (35) to cool the motor (20) before the refrigerant is led to a second stage compression element (40). The refrigerant is discharged from the second stage compression element (40) out of the compressor after it is further compressed in the second compression element (40). Thus, the motor (20) is cooled in a simple cooling mechanism during normal operation of the compressor.

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.
