Abstract: A method of manufacturing an electron emission device includes the steps of (a) forming a cathode electrode on a substrate, (b) forming an emitter on the cathode electrode by patterning, (c) forming a photosensitive glass paste layer burying the emitter by coating and drying the photosensitive paste layer on the surface of the substrate fabrication in which the emitter is formed, and (d) forming a gate insulating layer by patterning the result of step (c) by exposing, developing and calcining the photosensitive glass paste layer. The number of steps of the method of manufacturing an electron emission device is reduced and the processes are simplified due to self-alignment, and thus the manufacturing cost is reduced. The electron emission device is used as an electron emission type backlight unit and/or in an electron emission display device.
