Abstract

PURPOSE:To produce the high resolution Braun tube having high brightness with high yield, by constructing the fluorescent face of fluorescent stripe with two colors while setting the specific relation between the effective diameter of the hole in the shadow mask and the effective diameter in the horizontal direction of the picture image screen thereby providing the feature of the stripe type. CONSTITUTION:The fluorescent material regions 2 are arranged approximately in parallel while comprised of two colors such as red R and green G, for example, arranged alternatively while the black or non-light emission layer 3 is provided between each color. The hole 5 in the shadow mask 4 is arranged approximately in parallel with the fluorescent material stripe while one row of holes 5 will correspond with the adjoining two fluorescent stripes or a pair of two colors R, G in the fluorescent material region 2. Assuming the diameter of the opening in the direction perpendicular with said row of said holes in the shadow mask is dMmm. while the effective diameter in the horizontal direction of the picture image screen is Dmm.,dM<= DX0.00050 or preferably 0.00042mm..
