Abstract
In a method of manufacturing an image display apparatus, a first member having an electron-emitting device and a second member having a phosphor which is irradiated with an electron emitted from the electron-emitting device to emit light are seal-bonded in a seal bonding chamber in which a vacuum atmosphere is realized. An aging step for the electron-emitting device is performed before the step of seal-bonding.

A method of manufacturing an image display apparatus, comprising
- a step of seal-bonding a first member having an electron-emitting device and a second member having a phosphor which is irradiated with an electron emitted from the electron-emitting device to emit light in a seal bonding chamber in which a vacuum atmosphere is realized,
- wherein a step for aging the electron-emitting device is performed before the step of seal-bonding.
A method of manufacturing an image display apparatus, comprising
- the step of seal-bonding a first member having a plurality of electron-emitting devices and a second member having a phosphor which is irradiated with an electron emitted from the electron-emitting device to emit light in a seal bonding chamber in which a vacuum atmosphere is realized,
- wherein, before the step of seal-bonding, the characteristic adjustment step of selectively adjusting characteristics of the plurality of electron-emitting devices is performed.
A method of manufacturing an image display apparatus, comprising
- a step of seal-bonding a first member having an electron-emitting device and a second member having a phosphor which is irradiated with an electron emitted from the electron-emitting device to emit light in a seal bonding chamber in which a vacuum atmosphere is realized,
- wherein before the step of seal-bonding, the voltage application step of applying a voltage to the electron-emitting device subjected to the activation step is performed.
A method of manufacturing an image display apparatus, comprising
- the step of seal-bonding a first member having an electron-emitting device and a second member having a phosphor which is irradiated with an electron emitted from the electron-emitting device to emit light in a seal bonding chamber in which a vacuum atmosphere is realized,
- wherein, before the step of seal-bonding, the voltage application step of applying a voltage to the electron-emitting device having carbon and/or a carbon compound at electron-emitting portion and/or near an electron-emitting portion is performed.
A method of manufacturing an image display apparatus, comprising
- the step of seal-bonding a first member having an electron-emitting device and a second member having a phosphor which is irradiated with an electron emitted from the electron-emitting device to emit light in a seal bonding chamber in which a vacuum atmosphere is realized,
- wherein, before the step of seal-bonding, the voltage application step of applying, to the electron-emitting device, a voltage having a voltage value larger than a normal driving voltage value applied to the electron-emittting device at an image display operation is performed.
