Abstract
A phosphor screen (10) formed of respective color phosphor layers (9R), (9G), (9B) and respective color filter layers (4R), (4G), (4B) is formed on the inner surface of the panel (1). In that case, the respective color filter layers (4R), (4G), (4B) are respectively formed between the inner surface of the panel (1) and the phosphor layers (9R), (9G) and (9B). Therefore, the color cathode ray tube can be made high in contrast and in brightness.
