示管。 In a light source display tube configured to irradiate an electron beam emitted from an electron gun onto a phosphor screen to cause the phosphor screen to emit light, the electron gun includes a cathode that emits electrons, and a cathode that surrounds the cathode. The grid is composed of a cylindrical grid whose cathode side is open and the other end is provided with a mesh part, and the electrons emitted from the cathode are diffused at the position of the grid and converted into a non-focused beam. A display tube for a light source, characterized in that the phosphor screen is irradiated with light through a mesh part.
