<p>An electron-emitting device has an electric field impressing section (14) formed on a substrate (12), a cathode electrode (16) formed on one face of the electric field impressing section (14), and an anode electrode (20) which is provided on the one face and forms a slit (18) along with the cathode electrode (16). The electric field impressing section (14) is constituted of a dielectric. The electron-emitting device further has a modulation circuit (42) for controlling at least the amount of emitted electrons by modulating a pulse signal (Sp) impressed between the cathode electrode (16) and the anode electrode (20) according to a control signal (Sc) supplied from a control section (40) such as a CPU.</p> |
