Abstract
A display screen which does not have moire effects. The transparency of an intermediate subassembly, through which the observation is made, is substantially constant at the scale of an anode subassembly. The patterns of the intermediate subassemblies have a sufficiently low periodicity in at least one direction. This may be used in the production of display screens with micropoints.
