A display nucleus of a magnetic display element is disclosed. The display nucleus has a surface that is generally not perpendicular to the direction of the display element. This allows the display element to be shorter. The display nucleus is stable at various depth positions within the tube of the display element even though the transverse cross-sections of the display nucleus and display element are not necessarily the same. This is because the depth position stability of the display nucleus is provided either by a thin coating that can stick and re-stick to the tube of the display element or a compressible body that can fit into the display element. This reduces the rejection rate of display elements and display panels.
