Abstract:
1. An image display device comprising: a face substrate having an anode and phosphors on an inner surface thereof; a back substrate which has electron sources on an inner surface thereof and is arranged to face the face substrate with a given distance therebetween; and a sealing frame which is interposed between the face substrate and the back substrate while surrounding a display region and which holds the face substrate and the back substrate at the given distance; wherein end surfaces of the sealing frame and the face substrate and the back substrate are respectively hermetically sealed by way of a sealing material thus forming a vacuum envelope; wherein said vacuum envelope has an exhausting portion with an exhausting pipe formed in a stem glass; wherein an outer electrical lead hermetically penetrates into said stem glass of said exhausting portion at a position spaced from said exhausting pipe so as to electrically contact said anode; and wherein said anode is disposed on the inner surface of said face substrate without extending to an end of said face substrate.
