    • The present invention provides a reflector having a light-diffusing property which suppresses inter-object reflection over a wide angle, and giving particularly high reflectance in an intended range of viewing angle; and to provide a reflection type liquid crystal display device using the same. The reflector includes a plurality of light-reflective concave portions. Each of the concave portions is formed so that an inclination angle (an angle between a plane tangential to a point on a concave surface and the surface of the base material) is maximum on a side portion of the curved surface, and so that the direction of the side portion having the maximum inclination angle is on a far side from a view point of an observer. Moreover, the reflector includes many concave portions formed on a reflector surface, an inner surface of each of the concave portions-including a peripheral curved surface and a bottom curved surface that are continuously connected to each other, the peripheral curved surface being a part of a first sphere having a first radius, the bottom curved surface being a part of a second sphere having a second radius different from the first radius, and the bottom curved surface being located within the peripheral curved surface, wherein the first radius is smaller than the second radius, and a normal line extending from a center of the first sphere to the reflector surface and a normal line extending from a center of the second aphere to the reflector surface are not collinear. Further, the reflection type liquid crystal display device is provided with the reflector.

    • With regard to a solid polymer based fuel cell, an electrolyte membrane for conducting proton between a fuel electrode and an air electrode is conventionally made from a material obtained by chemically modifying a hollow fullerene such as C60 by means of a proton dissociable group. However, this fuel cell poses a following problem: since the proton conductivity of the membrane is so low that the internal resistance of battery is increased, which, when big current is extracted, causes the electromotive force to be reduced. The electrolyte membrane is made of a material obtained by chemically modifying an endohedral fullerene doped with an atom whose electronegativity is equal to or higher than 3, by means of a proton dissociable group, or a material made from an endohedral fullerene doped with an atom whose electronegativity is equal to or lower than 1. The membrane ensures the improved proton conductivity and reduced internal resistance of battery, as compared with the conventional electrolyte membrane made from a material obtained by chemically modifying a hollow fullerene by means of a proton dissociable group.

    • Organic materials doped with alkali metal have been conventionally used for electron transport layers or electron injection layers which constitute light-emitting films in organic EL light-emitting elements which are used in display devices or illuminating devices. Such conventional organic materials involve problems such that a strict process control is required since the alkali metal is highly reactive and thus, likely to be formed into a hydroxide, such that the resulting light-emitting element or light-emitting device needs complete sealing, and such that life of the light-emitting element cannot be sufficiently long. The present invention uses an alkali metal-including fullerene or an organic material doped with an alkali metal-including fullerene for electron transport layers or electron injection layers which constitute light-emitting films in organic EL light-emitting elements. The alkali metal-including fullerene or the organic material doped with an alkali metal-including fullerene is not very reactive with moisture or other impurities in the atmosphere and thus, the process control thereof is easy. Furthermore, even with a simple sealing structure, the resulting light-emitting element can be sufficiently long life.
    • 通常使用掺杂有碱金属的有机材料用于在用于显示装置或照明装置的有机EL发光元件中构成发光膜的电子传输层或电子注入层。 这样的常规有机材料存在这样的问题,即由于碱金属反应性高,因此很可能形成氢氧化物,所以需要完全密封所得的发光元件或发光元件,因此需要严格的工艺控制, 使得发光元件的寿命不能足够长。 本发明使用含有碱金属的富勒烯或掺杂有含碱金属的富勒烯的有机材料用于在有机EL发光元件中构成发光膜的电子传输层或电子注入层。 含有碱金属的富勒烯或掺有含碱金属的富勒烯的有机材料与大气中的水分或其他杂质不很好反应,因此其工艺控制容易。 此外,即使采用简单的密封结构,所得的发光元件也可以具有足够的使用寿命。
