[0058] 1 g of CNT powder (CNT, SWNT), 25 g of polyacrylate as acrylic resin, 2 g of photoinitiator HSP 188 (manufactured by SK UCB Co., Ltd.) and 6 g of Petia as photopolymer were added to 40 g of terpene Pinol was added and stirred to manufacture a paste composition for forming an electron emission source having a viscosity of 30,000 cps.

[0059] Pattern an ITO cathode electrode in a line shape on a glass substrate, apply a composition for forming an electron emission source thereon, and then irradiate it at 1000 mJ / cm using a parallel exposure system 2 exposure energy. Then, the resultant was developed with acetone, thereby forming a composition for forming an electron emission source in the electron emission source forming region.

[0060] The resultant was coated with a photosensitive glass paste composition and dried to form a photosensitive glass paste layer. Then irradiate it with 300mJ / cm from the back of the substrate 2 exposure energy. Sodium carbonate salt was ...

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.

Description

technical field [0001] The present invention relates to a method for manufacturing an electron emission device, an electron emission device manufactured by the method, a backlight unit including the electron emission device, and an electron emission display device, and more particularly, to a method in which photosensitive glass paste is used. paste) to simplify the manufacturing process of an electron emission device, an electron emission device manufactured by the method, and a backlight unit and an electron emission display device including the electron emission device. Background technique [0002] In general, electron emission devices can be classified into those using a thermionic cathode and those using a cold cathode as an electron emission source. Electron emission devices using cold cathodes as electron emission sources include field emitter array (FEA) type devices, surface conduction emitter (SCE) type devices, metal insulator metal (MIM) type devices, metal insu...
