However, this method requires a process of applying the paste and arranging and loading the spacers, so that it requires a large period of time to manufacture the entire electron emission display
In addition, the substrate may be contaminated due to errors in arranging the spacers and contamination of the paste applied to the spacers
In addition, the spacer should be accurately arranged between the light-shielding film of the anode substrate, thus requiring high precision and very expensive equipment
In addition, in the screen printing method, the screen printing process is repeated many times to meet the needs of fine pitch, and the maximum height of the spacers is limited

The present invention relates to an electron emission display and a method of manufacturing the same. The electron emission display includes: a cathode substrate having at least one electron emission device; a lower partition wall selectively formed in a predetermined region on the cathode substrate; an anode substrate having an image display region corresponding to the electron emission device; and optionally An upper partition wall is formed on the anode substrate facing the cathode substrate. The lower and upper partition walls support the cathode and anode substrates and maintain a predetermined distance between the cathode and anode substrates, and the lower and upper partition walls include foam glass. With this structure, the partition wall instead of the spacer is formed by selectively etching the foam glass and used to support the substrate, thereby omitting the process of loading the spacer. As described above, the method of manufacturing the electron emission display includes steps for forming each of the aforementioned elements.
Description
technical field [0001] The present invention relates to an electron emission display and a manufacturing method thereof, and more particularly, to an electron emission display and a manufacturing method thereof in which partition walls are formed instead of spacers by selectively etching foam glass, And the partition wall is used to support the substrate, thereby saving the process of loading spacers. Background technique [0002] Generally, electron emission devices are classified into a thermionic cathode type or a cold cathode type, wherein the thermionic cathode type and the cold cathode type respectively use a thermionic cathode and a cold cathode as an electron emission source. [0003] Cold cathode type electron emission devices include structures such as field emitter array (FEA), surface conduction emitter (SCE), metal insulator metal (MIM), metal insulator semiconductor (MIS), ballistic electron surface emission (BSE), and the like. [0004] By using such electron...
