Abstract
A display device mounted in a vacuum area between the front panel and the first base substrate of a CRT display which includes a plurality of second substrates having electron emitting elements. A plurality of deflection electrodes are mounted around the electron emitting elements and have heights which vary so that they decrease toward a peripheral portion of the second substrate for deflecting derived electrons outward to irradiate a fluorescent surface corresponding to the gaps between the second substrates. According to the plurality of second substrates and the deflection electrodes, a large sized display device can be manufactured.
