Abstract: A CRT panel glass and a CRT wherein a surface treating film is formed on an outer surface of a CRT panel so that overall transmittance distribution and reflectance distribution within an effective picture plane satisfy specific mathematical expressions, whereby, even with a flattened panel glass, brightness and contrast are uniform over the entire surface of the image display plane, and their production method.
