IMAGE DISPLAY APPARATUS AND PROCESS FOR PRODUCING THE SAME

摘要

With respect to an image display apparatus in which a low-melting-point metal layer is disposed on a metal layer superimposed on glass basal plate and two glass basal plates are bonded to each other in sealed form, it is intended to solve the technical problem of metal layer detachment or effacement during the manufacturing process. There is provided envelope (10) of image display apparatus comprising two glass basal plates (11,12) disposed opposite to each other with an interstice and, sealing given positions of these basal plates and defining an enclosed space between the two basal plates, sealing portion (33). This sealing portion comprises low-melting-point metal material (32) charged along given position and composite material layer (31a) interposed between a surface of glass basal plate and the low-melting-point metal material. The composite material layer contains frit glass and powdery metal whose solubility in the low-melting-point metal material in molten form at =500°C is <10%.
