Abstract
A black matrix color cathode-ray tube includes red, green, and blue luminescent patterns, wherein each of the red luminescent patterns has a wider area than each of the green and the blue luminescent patterns. The red, the green, and the blue luminescent patterns may be either of stripe or of dot shape. Preferably, the green and the blue luminescent patterns have a common area. More preferably, each green luminescent pattern has a wider area than each blue luminescent pattern. The cathode-ray tube displays one of red, green, and blue colors even when ones of the red, the green, and the blue luminescent patterns are selectively excited concurrently with others of the red, the green, and the blue luminescent patterns undesirably excited.
