Abstract:
1. A field emission display device having pixels, a signal line driver circuit and a scanning line driver circuit, each of the pixels comprising: an electron source element, from which electrons are emitted by applying a voltage between a first electrode and a second electrode; a capacitor element; a first signal line; a first switch, by which connection of one of electrodes of the capacitor element and the first signal line is selected; a second switch, which is switched over between ON and OFF in accordance with a voltage preserved in the capacitor element; a second signal line connected to the first electrode of the electron source element through the second switch; and a third switch for short-circuiting two electrodes of the capacitor element, wherein the pixels, the signal line driver circuit, and the scanning line driver circuit are provided on a same substrate.
