Optical filter layers that transmit only light with a desired wavelength are provided in a non-formation region of an optical absorbing layer formed on an inner surface of a glass panel, and phosphor layers that emit either one of red, green, and blue light are provided on the optical filter layers. The optical filter layers transmit blue light. Assuming that the thickness of the optical filter layer underlying the phosphor layer that emits blue light is t 1 , and the thickness of the optical filter layers underlying the phosphor layers that emit red and green light is t 2 , a relationship: t 1 >t 2 is satisfied. Because of the above configuration, a color cathode-ray tube is provided, which can be produced at low cost with satisfactory yield with less peeling of a phosphor layer.
