ABSTRACT:
A holographic display apparatus has a display section including a back plate, on which a cold cathode device of the field emission type having a great number of fine emitter electrodes is arranged. The display section includes a transparent and conductive front plate, on which a great number of anode electrodes, which define pixels, are arranged respectively opposite the emitter electrodes. The emitter electrodes are selected so as to emit electrons by an input signal prepared in accordance with the interference pattern of a holographic diffraction figure. The anode electrodes are excited and induced by electron rays from the emitter electrodes to change their reflection coefficient. The interference pattern is displayed on the basis of the change in the reflection coefficient of the anode electrodes.
