    摘要: A phosphor is formed with a glass coating layer on a surface of a phosphor grain to have improved moisture and/or thermal stability. A method for manufacturing the phosphor comprises preparing phosphor grains excitable by light, and forming a glass coating layer on a surface of each phosphor grain. The glass coating layer may be formed by mixing the phosphor grains with a glass composition; heat-treating a mixture of the phosphor grains and the glass composition to make the glass composition melt and surround the phosphor grains; and cooling and breaking the heat-treated mixture to provide phosphors, each comprising the phosphor grain having the glass coating layer formed on a surface of the phosphor grain.

    摘要: A thin-film transistor array is suited for the manufacture of an image display utilizing liquid crystal. In the thin-film transistor array, a first electrically conductive layer made principally of aluminum is selectively formed on one surface of a substrate. The first electrically conductive layer contains, as an impurity, a high-melting point metal which can be anodized. An oxide layer is formed by an anodization process on the first electrically conductive layer, and the first insulating layer is formed on the oxide layer so as to overlay the substrate. Furthermore, a first semiconductor layer made principally of silicon is selectively formed on the insulating layer, and a pair of second semiconductor layers made principally of silicon containing phosphorus are formed on the first semiconductor layer. A pair of second electrically conductive layers are formed on the paired second semiconductor layers, respectively.
