Abstract
A method of alignment of components of a field emission display comprising the steps of: attaching a first alignment barrier to a cathode substrate including electron emitters; positioning a gate frame against the first alignment barrier such that the gate frame is aligned with the cathode substrate; and sealing the gate frame in position against the first alignment barrier to the cathode substrate. The gate frame is a discrete component manufactured separately from the cathode substrate. A second alignment barrier is attached to the gate frame and an anode plate is positioned and sealed against the second alignment barrier such that the anode plate is aligned with the gate frame.
