Abstract

An electron emission structure according to embodiments of the inventive concept includes a cathode electrode and electron emission yarns each having a yarn shape and disposed in the cathode electrode. Here, the cathode electrode includes a plurality of first conductive panels spaced apart from each other in a first direction and at least one second conductive panel that crosses the first conductive panels in the first direction. Also, each of the first conductive panels includes at least one groove at an upper portion thereof. The second conductive panel is inserted to the groove of each of the first conductive panels. Each of the electron emission yarns is disposed between the first conductive panels. Each of the electron emission yarns contacts the second conductive panel. Each of the electron emission yarns is mechanically fixed and vertically aligned as well as arranged regularly by the second conductive panel and one pair of adjacent first conductive panels of the first conductive panels.
