Abstract
A display apparatus capable of preventing deterioration in the light emission efficiency of a fluorescent member thereof, that of the emission performance of the emitter thereof and shortage of the life caused from the deterioration in the emission performance. The display apparatus according to the present invention has the structure such that each of insulating support rods for supporting an anode substrate and a cathode substrate in the container of the display apparatus has a glass fiber support rod body made of a non-alkali material and the surface of the support rod has a coating layer made of a hydrophobic material so as to prevent diffusion of alkali components and generation of oxygen from the insulating support rods.
