FLAT DISPLAY
Disclosed here is a flat display having a pair of glass substrates and a sealing member applied on the periphery of the glass substrates. The glass substrates are oppositely disposed to each other at intervals therebetween. The glass substrates contain silicon as a component, while the sealing member contains bismuth. A protection layer and an insulating layer as an intermediate layer, which has a silicon-content lower than the glass substrates, are formed on the interface between the glass substrates and the sealing member. The structure above reinforces bonding strength of the sealing section, providing a highly reliable flat display.
1 . A flat display comprising:
a pair of silicon-contained glass substrates oppositely disposed at intervals therebetween; and
a bismuth-contained sealing member disposed on a periphery of the pair of glass substrates,
wherein, an intermediate layer whose silicon-content is lower than that of the glass substrate is disposed at an interface between the glass substrates and the sealing member.
2 . A flat display comprising:
a front substrate further including:
a glass substrate on which display electrodes are formed;
a dielectric layer disposed on the glass substrate so as to cover the display electrodes; and
a protection layer disposed on the dielectric layer; and
a back substrate disposed opposite to the front substrate, the back substrate further including:
a glass substrate to be paired with the glass substrate of the front substrate;
an data electrode disposed on the glass substrate; and
an insulating layer that covers the data electrodes; and
a bismuth-contained sealing member for sealing a periphery of the front substrate and the back substrate,
wherein, an intermediate layer whose silicon-content is lower than that of the glass substrates is disposed at an interface between the glass substrates and the sealing member.
