A sealing composition which can be suitably used for sealing a panel and a funnel of a color television tube is disclosed. The composition consists essentially of 60 - 99 wt.% of low melting devitrifiable glass powder, 1 - 35 wt.% of lead titanate powder and 0 - 5 wt.% of zircon powder. The glass powder has a composition of 77 - 83 wt.% of PbO, 7 - 10 wt.% of B.sub.2 O.sub.3, 7 - 12 wt.% of ZnO and 1 - 3 wt.% of SiO.sub.2.

Sealing composition

Here is disclosed a liquid crystal cell comprising a juxtaposed couple of planar elements at least one of which is transparent and a liquid crystal material interposed between said planar elements and sealed around the edges thereof, said cell being thermally and chemically stable, hermetically sealed and uniformly spaced, due to the use of low-melting glass as a sealant or a sealant-spacer.
