ABSTRACT:
In a flat-shaped display apparatus has a face plate, a rear plate, side plates, and necessary electrodes therein, a supporting plate and plural supporting rods which are connected to an edge of the supporting plate at intervals of a certain distance are provided between the face plate and the rear plate. The supporting rods are made of metal and all bonded parts are covered by guide plates so that no adhesive is exposed to the electron beams. Therefore, over-scanning of the electron beams can be made, without the electron beams impinging on the adhesive thereby enabling effective distortion compensation.
