Furthermore, for the holding means provided on the electron beam source side,
Because the structure connects adjacent members, the spacing between the deflection electrodes at the boundary of the unit is kept constant, and even when atmospheric pressure acts on the electrode members, the spacing does not change. When atmospheric pressure is applied to the support means, the support means receives a large pressure and is tightly adhered to the support means. Therefore, there is no possibility that relative displacement will occur due to thermal expansion of the front plate, and there will be no damage to the phosphor due to relative displacement.
