Abstract

PURPOSE:To precisely maintain a gap between a substrate glass and a faceplate glass by providing step sections on side faces of a glass spacer, holding low- melting point glass, and forming an airtight structure. CONSTITUTION:A glass spacer 13 is put in direct contact with a substrate glass 1 and a faceplate glass 12 to maintain a gap, it is hermetically sealed by low-melting point glass 15 held at step sections 14 on its side faces. A grid electrode groove 16 and a focusing electrode groove 17 are formed on the inner wall face of the glass spacer 13. A grid electrode 7 and a focusing electrode 8 can be positioned against the substrate glass 1 and the faceplate glass 12 with high precision.
