Abstract:
A method of manufacturing a spacer interposed between a first substrate having an image-forming member and a second substrate having an electron-emitting device, comprising the steps of:(A) preparing a glass preform; (B) stretching part of the glass preform while heating the glass preform by a heater; (C) cutting the stretched glass preform into a desired length; (D) applying a conductive material-dispersed or conductive material-dissolved liquid to an end portion of a spacer substrate formed by cutting the stretched glass preform into a desired length; and (E) heating the liquid applied to the spacer substrate to form an electrode at the end portion of the spacer substrate; wherein the stretching step has the step of feeding the glass preform at a velocity v1 toward the heater, and stretching the glass preform heated by the heater in a direction away from the heater at a velocity v2, and the velocities v1 and v2 have different speeds and satisfy a relation: v12.
