Abstract
A plasma display panel has spaced apart and parallel first and second substrates. A base glass layer is provided on one surface of the second substrate confronting the first substrate. A plurality of spaced apart parallel ribs are positioned on the base glass layer and between the first and second substrates. Each rib defines a channel with a neighboring rib. A plurality of phosphors capable of emitting light are provided, each of which is positioned a corresponding channel. In particular, the base glass layer and/or ribs are made of material substantially impermeable to and non-reflective of light.
