| abstract | (57) [Problem] To provide a carbonate-containing electron-emitting film used for a cathode of a cathode ray tube display device, by reducing the surface roughness of the electron-emitting film and increasing the size of the carbonate particles to improve the image quality. Improve and enhance electron emission ability. SOLUTION: A coating solution containing carbonate powder is prepared by dispersing a mixed solution of carbonate powder and a solvent in a container by rotating and stirring at a peripheral speed of 40 m / s or more. The average particle diameter D50 is set to 3 μm or more without destroying the primary particles of the salt. Thereafter, the salt is applied to the surface of the base metal of the electron gun. 50 μm thick film containing carbonate powder on base metal m, the surface roughness Rmax is 25 μm or less, and the average particle diameter D50 of the carbonate powder is 3 μm or more. As a result, an image display device with high image quality and luminance can be obtained. |
