Patent ID: 7326666

Claim:
Glass for forming barrier ribs, which consists, as represented by mol % based on the following oxides, essentially of from 24 to 50% of SiO 2 , from 13 to 23% of B 2 O 3 , from 10 to 32% of ZnO, from 3 to 20% of Li 2 O, from 1 to 9% of Na 2 O, from 1 to 15% of Al 2 O 3 , from 0 to 20% of MgO+CaO+SrO+BaO, and from 0 to 9% of Bi 2 O 3 , wherein ((B 2 O 3 +ZnO)—Al 2 O 3 ) is at least 24 mol %; in a case where ZrO 2 is contained, its content is at most 2 mol %; and neither PbO nor F is contained.
