ABSTRACT:
An image display apparatus comprises an electrode showing an electric potential defined to be high and an electrode showing an electric potential defined to be lower than the high electric potential, the electrodes being arranged vis-à-vis, at least one of the electrodes having a part showing a thickness of not less than 2 μm and a part located closest to the other electrode and showing a surface roughness of not more than 0.5 μm. With this arrangement, the image display apparatus can effectively suppress an electric discharge from taking place between electrodes and occurrence of a problem of broken wire.
