Color cathode ray tube having fluorescent substance particles with wave length selective layer

A color cathode ray tube, comprising:

• a glass panel;
• black matrix films formed on an inner surface of said glass panel, said black matrix films having a plurality of light transmission window portions with a predetermined positional relation and fluorescent substance films formed by fluorescent substance particles of green, blue and red at said light transmission window portions,
• wherein said fluorescent substance films have wave length selective layers partly coated on a surface of at least one kind of said fluorescent substance particles of green, blue and red, each of said wave length selective layers having a wave length selective characteristic, and
• wherein said fluorescent substance particles are formed in such a manner that said wave length selective layers are oriented towards said light transmission window portions on the inner surface of said glass panel.
