Next, a sandblasting process is performed through a sandblasting mask 7. Thereafter, a sintering process is performed. Thus, fluorescent screens are formed on a glass substrate 1 and the wall surfaces of barrier ribs 2. As the sandblasting mask 7, a photoresist 4 is used. By a photolithographic method, a desired pattern of the sandblasting mask 7 can be used. In this manner, fluorescent screens can be formed on the wall surfaces of the barrier ribs as well as the glass substrate 1. The fluorescent screens formed on the wall surfaces of the barrier ribs are in such a parabolic shape that a discharging space defined by the fluorescent screen is widened toward a front plate 11. | |
