Abstract
A plurality of electron-emitting devices arranged in a matrix, a row wiring that connects electron-emitting portions of electron-emitting devices arranged in the same line to one another, and a column wiring that connects gate connection members of electron-emitting devices arranged in the same column to one another are included. Each of the plurality of gates is positioned at one side of an electron-emitting portion in an arrangement direction in which the plurality of electron-emitting portions are arranged.
Claims19
An apparatus comprising:
- a rear plate configured to include a plurality of electron-emitting devices arranged in a matrix, each of which includes a plurality of electron-emitting portions arranged in a line, a cathode connection member that connects the plurality of electron-emitting portions to one another, a plurality of gates, each of which is positioned near a corresponding one of the plurality of electron-emitting portions, and a gate connection member that connects the plurality of gates to one another, a plurality of row wirings, each of which connects cathode connection members of electron-emitting devices arranged in a same row from among the plurality of electron-emitting devices to one another, and a plurality of column wirings, each of which connects gate connection members of electron-emitting devices arranged in the a column from among the plurality of electron-emitting devices to one another;
- and
- a faceplate configured to include an anode that accelerates electrons emitted from the plurality of electron-emitting devices and light-emitting members that emit light upon being bombarded with the electrons,
- wherein each of the plurality of gates is positioned at one side of an electron-emitting portion positioned near the gate in an arrangement direction in which the plurality of electron-emitting portions are arranged, and
- wherein a resistance of the gate connection member between a connection portion of the gate connection member connected to a gate positioned at the one end in the arrangement direction and a connection portion of the gate connection member connected to a column wiring is greater than a resistance of the gate connection member between a connection portion of the gate connection member connected to a gate positioned at the other end, which is opposite the one end.
