Abstract
An image-forming apparatus includes a first substrate, a second substrate, and a spacer that defines the spacing between the first substrate and the second substrate. The spacer has a portion ruggedized with grooves on the surface thereof exposed in the space between the first substrate and the second substrate. The grooves extend in a striped fashion substantially parallel with the first substrate and the second substrate. The ruggedized portion includes a plurality of regions, which are different from each other, in the ruggedized configuration. The image-forming apparatus thus controls an electron beam with a high accuracy, with no disturbance caused by the spacer.
