Abstract

PURPOSE:To enhance the uniformity of the emission of a cathode-ray tube by making the white luminous layer of a luminous layer to consist of two layers of given composition or a layer of given composition. CONSTITUTION:A luminous layer 6 is constituted of dot-like green luminous layers 7, red luminous layers 8 and white luminous layers 9. The white luminous layer 9 consists of either a layer prepared from a mixture of three kinds of phosphors, ZnSiAg, (ZnCd)SiAg and ZnSiAu:Al, or two layers that are a lower layer 10 prepared from a simple compound represented by ZnSiAu:Al and an upper layer 11 prepared from a mixture of a phosphor represented by ZnSiAg and a phosphor represented by (ZnCd)SiAg.
