ABSTRACT:
An image display device has a control electrode which comprises an X-Y grid assembly composed of planar two-layer conductive grids which define electron passage holes at junctions thereof. The control electrode have capacitive bodies disposed at the junctions for storing a control voltage to control electrons emitted from a planar cathode and having passed through the electron passage holes. A high-voltage electrode applies a high voltage to a planar light emitting layer to attract the electrons that have passed through the electron passage holes and have been controlled by the control voltage, to the planar light emitting layer for emitting light in response to bombardment of the electrons thereon. The electrons are supplied at all times by the control electrode for continuous emission of light from the planar light emitting layer. Since the cathode and the electrodes are of a planar structure, the image display device is lightweight and of a low profile.
