Abstract
An electron-emitting device is provided which includes a laminate having an insulating layer held between a pair of electrodes opposing each other, wherein an electron-emitting region insulated from the electrodes is formed at a side end surface of the insulating layer formed at the part at which the electrodes oppose each other, and electrons are emitted from the electron-emitting region by applying a voltage between the electrodes. A method for preparing the electron-emitting device is also provided.
