    Abstract: PROBLEM TO BE SOLVED: To prevent drop in luminescent efficiency of a fluorescent material, deterioration in emission capacity of an emitter, and shortage of life by using a glass material containing no alkali ingredient in a support, and making the surface of the support hydrophobic. SOLUTION: An insulating support 3A is arranged as a support for holding a cathode substrate 10 and an anode substrate 4. A non-alkali glass fiber containing no alkali ingredient is used as the material for a support main body 3a of the support 3A. As the non-alkali glass fiber, practically, a quartz fiber or an E glass fiber which is a kind of boron silicate is used. Generation of alkali ingredient diffused in a production process and during display device driving is suppressed, and drop in emission efficiency of a fluorescent material dot pattern can be prevented. A hydrophobic coating layer 3b is formed on the support main body 3a of the support 3A, the moisture content on the surface of the support 3A is reduced, and deterioration in emission capacity of an emitter and the shortage of device life can be prevented.
