Abstract
A plane type display device having a plurality of electric field emitting type cathodes (K), a high-tension electrode which fixedly gives on a surface of the plurality of cathodes (K) a strong electric field forming a Schottky barrier capable of making possible electron emission from the plurality of cathodes (K), a two-dimensional MOS gate array which is connected to the plurality of cathodes (K) and controls presence or absence of the electron emission from the plurality of cathodes (K) and a fluorescent substance layer (P) made to brighten by bombarding of the electrons selectively emitted from among the plurality of cathodes (K), whereby in a plane type displaying apparatus comprising a plurality of electric field emitting type cathodes and a fluorescent substance layer made to brighten by bombarding of electrons emitted from a cathode selected out of the plurality of electric field emitting type cathodes, a plane type displaying apparatus which is capable of making lower a driving voltage for having the plurality of cathodes selectively emit the electrons, reducing power consumption as well as performing a high speed operation is obtained.
