Abstract:
1. A display device in which a back substrate having a large number of cathode lines which extend in one direction and are arranged in parallel in another direction which crosses one direction formed on an inner surface thereof and a front substrate having anodes and phosphors formed on an inner surface thereof are arranged to face each other in an opposed manner with a given distance therebetween, wherein the large number of cathode lines define at least two different types of gaps x distance holding members which define the distance between the back substrate and the front substrate are provided in at least some of the gaps x a plurality of cathode lines are formed into groups and the gap between the groups which are arranged close to each other is set larger than the gap between the cathode lines belonging to the same group, and the cathode lines are extended in one direction in a zigzag pattern and the gap between the neighboring groups is displaced in the direction which crosses the extending direction of the cathode lines corresponding to the zigzag pattern of the cathode lines.
