Abstract
A gas discharge display panel in which opaque bus electrodes are structured in a frame shape for making each display cell clear as viewed from outside of the front substrate, and the bus electrodes function as a black matrix of the display screen. Hence the integrity of the black display status is improved and the contrast is increased.
