Abstract
A method of high precisely manufacturing, for an electron beam displaying apparatus, a support member which is equipped with an electrode on the surface thereof is provided. In this method, an electrode region is formed on the surface of a base material, the surface of the base material is ground by using a grinding stone having a convex portion, and at the same time a fringe portion of the electrode region is ground to form an electrode.
Claims2
A method of manufacturing a support member to be used in an electron beam displaying apparatus in which an electron source for emitting electrons and an electron-irradiated member to which the electrons emitted from the electron source are irradiated are oppositely arranged via the support member, the method comprising:
- forming, on a surface of a base material, an electrode region of which resistance is lower than that of the base material;
- and
- forming, with use of a grinding stone having a convex portion, a concave portion on the surface of the base material by grinding a portion on the surface of the base material where the electrode region has been formed, and an electrode by grinding a part of the electrode region.
