Abstract

PURPOSE: To improve luminous brightness sharply and contrast by using fluorescent material composed in such a way alkali metal compound is mixed with or coated on ZnO:Zn system fluorescent material.
CONSTITUTION: To begin with, wiring conductors 2 are coated on a substrate 1 composed of insulating material, such as glass, ceramics, which are covered with insulating layers 3 which have through-holes 3a formed at settled positions. And anode conductors 4 formed on the insulating layers 3 are connected the through- holes 3a to the wiring conductors 2, for example, anodes 6 are formed by coating fluorescent layers 5 formed in such a way that sodium hydride compound of alkali metal is mixed with ZnO:Zn system fluorescent material. A pattern display part 7 is formed by properly arranging these anodes 6. And, they are provided with control electrode 8 and cathode 9, and sealed by an enclosure 10. At least 0.001W1mol% of one type of either LiBH4 or NaBH4, etc. is used to 1mol of fluorescent material 1 as the sodium hydride compound of alkali metal.
