| 摘要 |
The invention relates to a gaseous discharge display device (gas panel) of the kind comprising a pair of glass plates each having an array of parallel conductors formed thereon overlaid with a dielectric layer, the plates being sealed together at their edges in superimposed spaced parallel relationship with the conductor arrays being disposed substantially orthogonally to one another to define a plurality of discharge gaps, each formed at the cross-point of a conductor of one array with a conductor of the other array, and metal spacers disposed between the dielectric layers for maintaining the discharge gaps precisely spaced over the area of the display device. The spacers are in the form of rods 9 having a trapezoidal cross-section so that light 13 or 15 emanating from an adjacent gas discharge tends to be reflected downwardly into the panel, as shown by rays 17 and 19, rather than outwardly from the panel. This reduces the visibility of the spacers 9 when the panel is viewed from the front. |
