ク・ブラウン管。[Scope of Claim for Utility Model Registration] 1. Electron beams emitted from three electron guns each responsible for the three primary colors of red, green, and blue are passed through a metal shadow mask with many small holes to control the spread of the electron beams. In a shadow mask cathode ray tube that emits a predetermined color by colliding with a phosphor coated on the fluorescent surface, we have discovered that a superconducting material layer with zero electrical resistance is provided between the shadow mask and the electron gun. Features a shadow mask and cathode ray tube. 2. The shadow mask cathode ray tube according to claim 1, characterized in that a cooling layer for cooling is bonded to the superconducting material layer. 3. The shadow mask cathode ray tube according to claim 2, wherein the cooling layer is provided with an electronic cooling element that exhibits a cooling effect depending on the direction of current flow.
