PURPOSE:To obtain a thin and compact display device by heating a cathode, emitting a thermion, accelerating a generated electron beam, and landing the final phosphor. CONSTITUTION:A number of cathode wires 2 are provided on a thin glass substrate 1. One more thin glass substrates 4 is provided on the glass substrate 1 through a spacer 3. A phosphor 5 is formed on this glass substrate 4 by a slurry machine, screen printing, gravure printing, etc. and then a lacquer coat and a metal back coat are formed on it. The coupling between the glass substrates 1 and 4 and the spacer 3 is performed using low melting glass. Furthermore, the glass substrate 1 is made to adhere to a thick glass substrate 6 using low melting glass and the whole is covered with a cup-shaped cover body 7. This cover body 7 is also made to adhere to the glass substrate 6 using low melting glass. A hole for inserting a chip tube must be provided in this cover body 7 so as to make the inner part vacuum. |
