Abstract
The present invention provides an electron emission device assured to emit electrons without requiring film thickness control on the order of submicrons and a production method of the electron emission device as well as a display apparatus using the electron emission device. The electron emission device includes a cathode electrode consisting of conductive fine particles adhered directly onto a substrate and electrons are emitted from these conductive fine particles when a predetermined electric field is applied.
