ABSTRACT:
A display device includes: a rear wall (4); a display panel (3) spaced from the rear wall (4) and a display screen (7) having a pattern of phosphor pixels; an addressing structure (100) disposed intermediate the rear wall (4) and the display panel (3) for addressing the display screen (7); and an aperture spacer plate (101); wherein, the spacer plate (101) includes a glass material having an electrical resistance of log R at 250.degree. C..gtoreq.8. The spacer plate (101) including a glass material having an electrical resistance of log R at 250.degree. C..gtoreq.8 reduces the charging of the spacer plate walls and improves uniformity of phosphor brightness. The spacer plate may further comprise a glass having a lower alkali mobility less than sodium lime glass.
