LIGHT SOURCE

WIPO Patent Application WO/2006/070445

A1

Light sources (10A, 10B) are provided with a light emitting part (14) whereupon a plurality of electron emitting elements (12A, 12B) are two-dimensionally arranged, and driving circuits (16A, 16B) for applying a driving voltage (Va) to each of the electron emitting elements (12A, 12B) of the light emitting part (14). The driving circuits (16A, 16B) apply the driving voltage (Va) to an upper electrode (18) and a lower electrode (20) of each of the electron emitting elements (12A, 12B), based on a control signal (Sc) from an external (a switch for turning on/off light, or the like) for indicating turning on/off, and each of the electron emitting elements (12A, 12B) is drive-controlled. Each of the electron emitting elements (12A, 12B) is provided with a board-shaped emitter part (22), the upper electrode (18) formed on a front plane of the emitter part (22), and a lower electrode (20) formed on a rear plane of the emitter part (22).
