Abstract
A method for manufacturing plasma display unit substrates having bulkheads by applying a mixture of ceramic powder or glass powder and a binder to a back face plate made of ceramics or glass. Bulkheads are formed on the back face plate by rolling a roll, having a plurality of grooves on its surface, over the mixture-applied surface of the back face plate while applying pressure to the surface with the roll. Alternatively, the grooves on the surface of the roll may be pre-filled with the moisture and rolled over the surface of a back face plate, thereby forming bulkheads.
