Abstract
The cathode-ray tube according to the present invention has on the inner surface of the funnel section of the body thereof a laminated layer comprising a first layer of black material, a metal backing layer and a second layer of black material. According to the configuration of the cathode-ray tube of the present invention, stray light reflected within the body of the cathode-ray tube is absorbed by the first layer of black material on the inner surface of the funnel, while stray light reflected off the inner surface of the funnel is absorbed by the second layer of black material. This makes it possible to reduce the amount of stray light incident upon the effective screen area of the panel section.
