Abstract
A light-emitting device having front and back panels combined together through a spacer and frit glass, wherein the frit glass is prevented from flowing onto a fluorescent surface or flowing out to the outer surface side of the spacer. A joint surface of the spacer on the front panel side is provided with a slanted surface spaced more from the front panel as the outer periphery of the light-emitting device is approached. Alternatively, a gap for accommodating frit glass may be provided at an outer side portion of the joint surface. Further, the front panel and/or the back panel may be joined to the spacer by frit glass which is applied to each joint surface of the spacer by screen printing.
