Abstract
In a substrate manufacturing process for color plasma displays, it is made possible to form a phosphor coat in a desirable form all over a panel by introducing a step to coat the whole surface of a luminescent display section with a paste containing white particulates of titanium oxide or the like, which are finer than phosphor powder, after barriers are formed on a back substrate and before the discharge cell inside is sequentially coated with phosphors for different colors to make up luminescent pixels. By applying the particulate paste to the unfired barrier portion, which is then in a very porous state, before the phosphor coating stage, collective firing of the barriers and the phosphor layers is made possible.
