Abstract: PROBLEM TO BE SOLVED: To avoid the generation of a moire phenomenon on a screen by having a transparent surface of a fixed ratio for a basic pattern along an axis parallel to the overall direction of cathodes, regardless of the position of this axis in the right-angled direction. SOLUTION: A basic pattern is formed of picture elements 25 in this case. The transparency of the picture elements 25 is constant from the end to end of the picture elements 25 in the direction of grid lines 17 by the pattern of cathode conductors 13 and the grid lines 17. That is, each picture element 25 includes an opaque surface of the same ratio along an axis parallel to the overall aligned direction of the cathode conductors 13, regradless of the position of this axis in the right-angled direction (that is, in the direction of the grid lines 17). A grid 3 includes linear sections 23, but these linear sections 23 are right-angled to anode strips so as not to be a hindrance to moire effect. A more phenomenon is therefore invisible from an observer regardless of the position of the observer to the cathode surface.

Abstract: The intermediate section is opaque and the shape of the individual symbols is adjusted to remove the moire distortion effect.
