Abstract
Each of spacers which defines an interval between substrates composing an envelope is fixed to the substrates while their linearity is kept by the tension exerted therein. In the fixation, it is set such that a fixing point of each of the spacers is located between points on which the tension is exerted. Thus, even when the tension is released, the linearity is maintained, so that a displacement of each of the spacers can be prevented to kept a high assembly accuracy.
Claims8
A method of manufacturing an envelope which includes a first substrate, a second substrate opposed to the first substrate, and a space defining member which is located between the first substrate and the second substrate and has a substantially plate shape, the method comprising:
- applying a tension to the space defining member;
- fixing the space defining member to the first substrate at fixing points thereon separate from each other while applying a tension to the space defining member;
- and
- releasing the tension from the space defining member fixed to the first substrate,
- wherein in the fixing of the space defining member to the first substrate, the fixing points of the space defining member to the first substrate are located between points at which the tension is exerted.
A method of manufacturing an electron beam apparatus which includes a first substrate having a plurality of electron-emitting devices on a surface thereof, a second substrate which is opposed to the first substrate and in which an electrode that controls electrons emitted from the plurality of electron-emitting devices is formed, and at least one space defining member which is located between the first substrate and the second substrate and has a substantially plate shape, the method comprising:
- applying a tension to the space defining member;
- fixing the space defining member to the first substrate at fixing points thereon separate from each other while applying a tension to the space defining member;
- and
- releasing the tension from the space defining member fixed to the first substrate,
- wherein in the fixing of the space defining member to the first substrate, fixing points of the space defining member to the first substrate are located between points at which the tension is exerted.
