Abstract
An electron emitting device, comprising: a first electrode provided on a substrate; a first layer provided on said electrode and capable of undergoing transition from an electrically high resistance state to a low resistance state when irradiated by a radiant ray; and a conductive layer, an insulating layer and a second electrode, laminated on said first layer. An electron generator includes the electron emitting device as well as an applicator for applying an electric field to said device, and an irradiator for irradiating a radiant ray on the device. A method for driving the electron emitting device is also provided.
