Patent ID: 6992440

Claim:
A light-emitting device having an airtight container constituted by a front substrate, a rear substrate disposed to face the front substrate and a spacer component disposed between the front substrate and the rear substrate to maintain a certain distance between the front substrate and the rear substrate, wherein a joint portion between the front substrate and the spacer component and a joint portion between the rear substrate and the spacer component, are sealed with sealing materials, at least one of the sealing materials used at the two joint portions is made of a sealing composition comprising a curable methylphenyl silicone resin and a refractory filler, the amount of the refractory filler based on the sum of the methylphenyl silicone resin and the refractory filler in the sealing composition, is from 10 to 80 mass %, and the methylphenyl silicone resin has a molar ratio of phenyl groups to methyl groups (i.e. mols of phenyl groups/mols of methyl groups) of from 0.1 to 1.2.
