Abstract
A flat display device preferably of the PALC type in which the plasma channels are formed by depositing successive layers of electrically conductive and electrically insulating material on a substrate containing spaced walls of a resist material that are preferably structured with a negative slope to form in the space between the resist walls flanking channel walls comprising an electrode layer and rising above it a wall of insulating material with the electrode layer sides exposed to adjacent channels. Subsequently, the resist walls are removed by a lift-off process removing with it the layer deposits on the resist walls leaving behind the layer deposits between the resist walls. The remaining insulating walls are then covered with thin dielectric sheet-like member to form the plasma channels.
