Abstract

PURPOSE:To obtain a uniform fluorescent screen by substantially extending both the fluorescent fine stripe and index fluorescent fine stripe groups against the effective screen limited by a light absorptive material. CONSTITUTION:The light absorptive material 11 is coated on the inside of the glass panel 10 and an effective screen is limited. Then the color fluorescent stripes 8 are subsequently formed. This color fluorescent stripe length has an ample allowance even when a picture image distortion occurs. After that, metal back is performed and the index fluorescent stripe 9 is formed on the surface. In this case, the ground has no difference in level. As a result, the index fluorescent stripe 9 can uniformly be formed up to its end.
