[0057] figure 2 is a projected schematic diagram of the electron-emitting device 101 according to the first embodiment of the present invention; image 3 yes figure 2 A schematic plan view of the electron-emitting device 101 is shown.
[0058] refer to figure 2 and image 3 , The electron emission device 101 according to the first embodiment of the present invention includes: a base substrate 110 , a first electrode 120 , a second electrode 130 , and an electron emission source 150 .
[0059] The base substrate 110 is a body part having a certain thickness, or a glass substrate made of quartz glass, glass containing a small amount of impurities (eg, Na), flat glass, glass coated with SiO2, alumina, or ceramics. If a flexible display device is to be implemented, the base substrate 210 may be made of flexible materials.
[0060] The first electrode 120 includes a first main electrode portion 121 and a first auxiliary electrode portion 123, the first main electrode portio...
