Abstract:
A method of forming barrier ribs for a display panel, comprising the steps of: forming a glass layer for an underlying layer having a first low-melting glass powder with a softening point of a temperature A dispersed in a vehicle, and a glass layer for a barrier-rib layer having a second low-melting glass powder with a softening point of a temperature B2 higher than the temperature A and a third low-melting glass powder with a softening point of a temperature B1 higher than the temperature A but lower than the temperature B2 dispersed in a vehicle, on a substrate in this order;heating up to sinter the glass layer for the underlying layer and the glass layer for the barrier-rib layer at a temperature Z higher than the temperature A but lower than the temperature B2, thereby burning out the vehicles therefrom, forming a carve-resistive underlying layer and a barrier-rib material layer easy to carve;forming a mask for carving in a pattern corresponding in plan to barrier ribs on the barrier-rib material layer, carving part of the barrier-rib material layer by a sand blasting method, and thereby forming barrier ribs for dividing a display area.
