Document Type and Number:
Japanese Patent JP2871579
Kind Code:
B2
Abstract:
There is provided a cold cathode including a substrate, a plurality of electron emitting electrodes formed on the substrate, a first insulating layer formed on the substrate and formed with a plurality of first cavities in which the electron emitting electrodes are disposed, a gate electrode formed on the first insulating layer and formed with a plurality of first openings which are in communication with the first cavities, a second insulating layer formed on the gate electrode and formed with a plurality of second cavities which are in communication with the first openings, and a focusing electrode formed on the second insulating layer and formed with a plurality of second openings which are in communication with the second cavities. At least one of central axes of the second openings and central axes of the first openings is eccentric with central axes of the electron emitting electrodes. Eccentricity between at least one of the central axes of the second openings and the central axes of the first openings, and the central axes of the electron emitting electrodes is oriented outwardly, and a degree of the eccentricity is set greater at a location more remote from a centrally located electron emitting electrode.
