Abstract
A manufacturing method of an image display apparatus, having a vacuum container with getters therein, includes the steps of exhausting an inner gas through an exhaust hole provided in the vacuum container; and activating the getters during the exhausting. In the activating step, the getters are sequentially activated first from a getter positioned in an area having a larger exhaust conductance with respect to the exhaust hole.
