<p>PURPOSE:To enhance the anti-moistening property, remove the coating process of glass frit to a spacer, and eliminate stress concentration at the bonded part by adhering the periphery of a glass sheet using a low melting point glass without using any spacer. CONSTITUTION:Two glass sheets 3, 3 are bonded at peripheries with a low melting point glass so as to have a certain gap, and a seal 4 is formed. As this seal does not use any spacer, the amount of low melting point glass increases accordingly, and it is heated at the time of bonding and wets on the glass sheets to present meniscus structure as shown in the attached illustration. This sealing with low melting point glass shall not necessarily be applied to the whole peripheral edges-the portion where electroluminescence element is encapsulate shall preferably be sealed with a glass having a lower melting point to prevent heat deterioration of the element. As no spacer is used in this manner, a process to coat frit to the spacer is no more necessary to lead to enhancement of the producibility, and forming of meniscus with the seal 4 and associate dispersion of stresses should allow the glass sheets to be made thinner to contribute to constructing in small size and light weight.</p> |
