Patent ID: 6936966

Claim:
A plasma display device having first and second substrates and a discharge gas filled therebetween, the plasma display device comprising: first and second electrodes extending in parallel to each other on the first substrate; and first and second discharge electrode parts extending from the first and second electrodes, respectively, so as to oppose each other; and a plurality of partition walls formed on the second substrate so as to extend perpendicularly to the first and second electrodes, the partition walls each separating an array of the first and second discharge electrode parts from an adjacent array of the first and second discharge electrode parts, wherein a discharge gap of a substantially constant width is formed between opposing, first and second discharge electrode parts, the discharge gap being defined by first and second edge parts of the opposing first and second discharge electrode parts, respectively; the first and second edge parts have lengths longer than widths of the first and second discharge electrode parts, the widths being measured in directions in which the first and second electrodes extend, respectively; the first edge part forms an angle θ with respect to the direction in which the first electrode extends, the angle θ satisfying a condition: 30°≦θ≦60°; and the width of each of the first and second discharge electrode parts is 120 μm or less; and the first and second discharge electrode parts extend toward each other in parallel with, but not overlapping, the partition walls.
