Abstract:
A display panel comprising:a glass backplate (1) having a thermal coefficient of expansion of between 2.8*10.sup.-6 and 10*10.sup.-6 K.sup.-1, a first surface (2) of which is provided with ribs (3) of sintered glass frit, which ribs have a substantially parallel direction and bound channels (4), said backplate (1) having electrodes (5) extending in the direction of the ribs (3);a plate-shaped front member (10) comprising glass having a thermal coefficient of expansion of between 2.8*10.sup.-6 and 10*10.sup.-6 K.sup.-1 and provided with light-transmissive electrodes (11) which extend transversely to the channels (4), said front member (10) resting on the ribs (3) and being connected to the backplate (1) in a gastight manner;an ionizable gas in the channels (4), characterized in that the glass frit comprises90 to 97.5% by weight of ZnO, B.sub.2 O.sub.3 and V.sub.2 O.sub.5, in which the mutual weight ratios of these components are between the points A, B, C and D of their ternary phase diagram, which points have the following compositions A:44;36;20, B:59.6;20.4;20, C:63.3;31.7;5 and D:50.7;44.3;5 (% by weight of ZnO; % by weight of B.sub.2 O.sub.3 ; % by weight of V.sub.2 O.sub.5),1.6 to 7% by weight of oxides chosen from CuO, PbO, and CuO plus PbO,0.2 to 1.2% by weight of SiO.sub.2, and0.5 to 2.5% by weight of BaO.
