Abstract

PURPOSE:To improve display contrast by mixing green coloring fluorescent material and red pigment particles of indium sulfide. CONSTITUTION:A fluorescent film 12 is provided at one side of an anode 11 consisting of an aluminum plate, etc. The anode 11 is supported by a ceramic substrate 13. A cathode 14 is provided, being opposed to the fluorescent film 12 provided at one side of the anode 11. The fluorescent film 12 is excited and fluoresces by low speed electron rays radiated from the cathode 14. The fluorescent film 12 is formed by a mixture of green coloring fluorescent material and red pigment particles of indium sulfide.
