Abstract
A spacer positioned between a faceplate and a rear plate so as to extend across a first region on which an anode is provided and into a second region on which the anode is not provided is included. The spacer includes a plurality of conductive members extending across a first section of a side surface of the spacer that underlies the first region and into a second section of the side surface of the spacer that underlies the second region, distances from the faceplate to the conductive members differing from each other. The plurality of conductive members have an end portion in the second section. The position of the end portion of a conductive member farther from the faceplate is farther from the end portion of the anode.
Claims3
An apparatus comprising:
- a rear plate configured to have an electron-emitting device;
- a faceplate configured to have an anode on part of a first region of a surface that faces the electron-emitting device;
- and
- a spacer configured to be positioned between the faceplate and the rear plate so as to extend across the first region and into a second region of the faceplate,
- wherein the spacer has a plurality of conductive members extending across a first section of a side surface of the spacer that underlies the first region and into a second section of the side surface of the spacer that underlies the second region, distances from the faceplate to the conductive members differing from each other, and
- wherein the plurality of conductive members have an end portion in the second section, and the position of the end portion of a conductive member farther from the faceplate is farther from the end portion of the anode in a direction parallel to the side surface of the spacer on which the end portion is positioned and parallel to the surface of the faceplate.
