The present invention provides a panel cathode ray tube that has a planar enclosure or tube structure consisting of a front panel and a rear panel that face each other, and provides a parallel structure between the front panel and the rear panel for supporting each electrode of the cathode ray tube. Mechanical support is provided between both panels by the cooperation of the arranged insulating support walls and the cross-shaped electrodes that are superimposed on these and constitute accelerating electrodes, so that the external pressure against the enclosure, that is, the atmospheric pressure, is sufficiently high. By being able to maintain mechanical withstand voltage, it is possible to create a large screen, that is, a large area.

BACKGROUND OF THE INVENTION Generally, a cone-shaped cathode ray tube having a configuration in which a neck tube in which an electron gun is housed extends rearward is mainly used as a general image display device. This cathode ray tube has a problem in that the depth due to the presence of the neck portion is extremely long compared to the size of the screen, and the space it occupies is large.

In contrast, in recent years flat, thin, or panel-type display devices have been significantly developed, such as EL (electroluminescence) display devices, plasma display devices, liquid crystal display devices, and the like. However, all of these devices are insufficient in terms of performance such as brightness and color reproducibility of contrast color display, and have not been put into practical use or for general use.

The position is advantageous in terms of high brightness and high contrast.
For example, as disclosed in Japanese Patent Publication No. 58-8546, various proposals have been made, but as the area becomes larger, it is necessary to obtain various characteristics of each part, and in particular, to improve the structure of the cathode ray tube. In this case, it is necessary to maintain a high degree of vacuum inside the tube, that is, the outer enclosure, and as this becomes larger, the front panel and rear flat panel facing each other, which make up the outer enclosure, become larger in area, and atmospheric pressure increases. A problem arises in that it becomes impossible to maintain a sufficient mechanical withstand voltage, and as a result, large-area panel cathode ray tubes have not yet been sufficiently developed.
