1. A plasma tube array-type display sub-module comprising:
an address electrode support sheet having a plurality of address electrodes formed thereon;
a display electrode support sheet having a plurality of display electrodes formed thereon; and
a plurality of plasma tubes each filled with a discharge gas, arranged in parallel and held between the address electrode support sheet and the display electrode support sheet as a plasma tube array, wherein
the plasma tube array is fixed to a sub-module frame through an intermediate layer which can deform along the surface shape of the address electrode support sheet on the back side.
2. The plasma tube array-type display sub-module according to claim 1 , further comprising:
an adhesive layer, which is a solvent type adhesive layer and bonds the address electrode support sheet to the plasma tubes in a condition in which the adhesive layer is not in contact with the intermediate layer.
3. The plasma tube array-type display sub-module according to claim 2 , wherein
a solvent type acrylic resin is used for both the adhesive layer and the intermediate layer.
4. The plasma tube array-type display sub-module according to claim 1 , wherein
the intermediate layer is formed so as to be in contact with a first adhesive layer, which bonds the address electrode support sheet that is divided by the plurality of plasma tubes and the plasma tubes, and a second adhesive layer, which bonds the display electrode support sheet and the plasma tubes, through a gap between the adjacent address electrode support sheets and a clearance between the adjacent plasma tubes.
5. The plasma tube array-type display sub-module according to claim 1 , wherein
the intermediate layer is formed so as to be in contact with a first adhesive layer, which bonds the address electrode support sheet that is divided by the plurality of plasma tubes and the plasma tubes, through a gap between the adjacent address electrode support sheets and a clearance between the adjacent plasma tubes, and a second adhesive layer, which bonds the display electrode support sheet and the plasma tubes, bonds the display electrode support sheet and the plasma tubes in a condition in which the second adhesive layer is not in contact with the intermediate layer.
6. The plasma tube array-type display sub-module according to claim 5 , wherein
a solvent type acrylic resin is used for both the first adhesive layer and the second adhesive layer.
7. A display device comprising
the plurality of plasma tube array-type display sub-modules according to claim 1 joined to one another.
8. A display device comprising:
a plurality of plasma tubes each filled with a discharge gas;
an address electrode support sheet on the back side having a plurality of address electrodes formed along a longitudinal direction of the plasma tubes;
a display electrode support sheet on the front side having a plurality of display electrodes extending in the direction of crossing all the plasma tubes; and
the plurality of plasma tubes arranged in parallel and held between the address electrode support sheet and the display electrode support sheet, wherein
a hard back support plate is provided through an intermediate layer having a flexibility to deform along the surface shape of the address electrode support sheet on the back side.
9. The display device according to claim 8 , wherein
the intermediate layer is made of a gel-like material with a Young's modulus of not less than 10 KPa and not more than 200 KPa.
10. The display device according to claim 8 , wherein
the back support plate is made of a hard plastic with a Young's modulus of not less than 1000 KPa and not more than 4000 KPa.
11. The display device according to claim 9 , wherein
the back support plate is made of a hard plastic with a Young's modulus of not less than 1000 KPa and not more than 4000 KPa.
12. A display device comprising:
a plurality of plasma tubes each filled with a discharge gas;
an address electrode support sheet on the back side having a plurality of address electrodes formed along a longitudinal direction of the plasma tubes;
a display electrode support sheet on the front side having a plurality of display electrodes extending in the direction of crossing all the plasma tubes thereon; and
the plurality of plasma tubes arranged in parallel and held between the address electrode support sheet and the display electrode support sheet; wherein
a hard back support plate with a noise reflecting function is provided through an intermediate member, having a noise absorbing function and a roughness absorbing function effected by deforming along the surface shape of the address electrode support sheet on the back side.
13. The display device according to claim 12 , wherein
the intermediate member is made of a gel-like material and the back support plate is made of a hard plastic.
