Abstract
A gas discharge display panel has front and rear plates. The plates are spaced apart from each other, thereby forming a chamber in which a discharge gas is contained. Also, both the front and rear plates are dark in color. Preferably, both the front and rear plates have a darkness of about 20% or more or a transparency of about 80% or less. This decreases halation of light, thereby preventing the mixing of colors. Also, the gas discharge display panel provides a high contrast and clear images to viewers.
