LEAD-FREE LOW-TEMPERATURE GLASS FRIT, LEAD-FREE LOW-TEMPERATURE GLASS FRIT PASTE MATERIAL USING IT, IMAGE DISPLAY DEVICE, AND IC CERAMIC PACKAGE

摘要

PROBLEM TO BE SOLVED: To provide a lead-free low-temperature glass frit in which dispersed state of a lead-free filler at a sealing part or a coating part is adequately controlled in consideration of specific gravity, particle size, and content of the lead-free filler against a lead-free low-temperature glass, and to provide a lead-free low-temperature glass frit material using it, an image display device and IC ceramic package.;SOLUTION: The lead-free low-temperature glass frit comprises lead-free low-temperature glass, a lead-free filler having a specific gravity smaller than that of the lead-free low-temperature glass and a lead-free filler having a specific gravity larger than that of the lead-free low-temperature glass. Wherein these lead-free fillers are different in the average particle size, preferably the average particle size of the lead-free filler having a specific gravity smaller than that of the lead-free low-temperature glass is larger than the average particle size of the lead-free filler having a specific gravity larger than that of the lead-free low-temperature glass.;COPYRIGHT: (C)2010,JPO&INPIT
