PROBLEM TO BE SOLVED: To improve reliability by suppressing manufacture defective by cracking in a dielectric thin plate, and setting thickness of a liquid crystal layer. SOLUTION: On a first base plate 8 having a discharge electrode forming part 15 on which a discharge electrode is formed to leave an outer circumferential edge part on one main surface 8a, and a protrusion forming part 16 on which plural protrusions having a predetermined height are formed on the outer circumferential edge part, dielectric thin plates are placed on the protrusions to be disposed at a given interval, and a frit seal member 11 as a frame-shaped seal part continuous between the discharge electrode forming part 15 and the protrusion forming part 16 is formed in such a way that at least one of two sides 11a, 11b is extended at a part where both sides 11a, 11b cross each other. In addition, the protrusion forming part 16 is not formed at a corresponding part of the extended part of the frit seal member 11. |
