Abstract

The invention provides a disassembling method for an image display apparatus, a producing method for an image display apparatus, a producing method for a support member and an image display unit, and a producing method for a working material. In particular, there is disclosed a configuration in which the disassembling of the image display apparatus is executed by inserting a substance between the image display unit and the support member.

Claims

1. A method for disassembling an image display apparatus in which an image display unit including an internal space and a support member for supporting the image display unit are adhered by an adhesive member, the method comprising:

a step of separating said image display unit and said support member, wherein said separating step includes a step of inserting a substance between said image display unit and said support member.

2. A disassembling method according to claim 1, wherein said adhesive member is cut by the insertion of said substance.

3. A disassembling method according to claim 2, wherein said substance cuts said adhesive member by contact with said adhesive member.

4. A disassembling method according to claim 1, wherein said substance is a solid.

5. A disassembling method according to claim 1, wherein the step of inserting said substance is a step of inserting a linear member.

6. A disassembling method according to claim 1, wherein the step of inserting said substance is a step of inserting a cutting blade.

7. A disassembling method according to claim 1, wherein said substance is a liquid.

8. A disassembling method according to claim 1, wherein the step of inserting said substance is a step of ejecting a liquid to said adhesive member.

9. A disassembling method according to claim 1, wherein said substance is a substance capable of softening said adhesive member.

10. A disassembling method according to claim 1, wherein said separating step includes a step of applying, at least to either of said display unit and said support member, a force in a direction of separating said display unit and said support member.

16. A method for producing an image display apparatus, comprising:

a step A of preparing an image display unit;

a step B of obtaining a support member by a disassembling method according to claim 1;

and

a step of combining the image display unit prepared in said step A and the support member obtained in said step B.

18. A method for producing an image display apparatus, comprising:

a step A of preparing a support member;

a step B of obtaining an image display unit by a disassembling method according to claim 1;

and

a step of combining the support member prepared in said step A and the image display unit obtained in said step B.

20. A method for producing an image display apparatus, comprising:

a step of obtaining an image display unit and a support member by a disassembling method according to claim 1;

and

a step of combining said image display unit and said support member obtained in said step.

22. A method for producing a working material, comprising:

a step of obtaining a support member by a disassembling method according to claim 1;

and

a step of rendering the support member obtained by said step easily workable.

24. A method for producing a working material, comprising:

a step of obtaining an image display unit by a disassembling method according to claim 1;

and

a step of rendering the image display unit obtained by said step easily workable.

11. A method for disassembling an image display apparatus in which an image display unit and a support member for supporting the image display unit are adhered by an adhesive member, the method comprising:

a step of separating said image display unit and said support member, wherein said separating step includes a step of pressing said image display unit in a direction separating from said support member, through an aperture formed in said support member from a surface thereof opposed to said image display unit to a surface at the opposite side.

17. A method for producing an image display apparatus, comprising:

a step A of preparing an image display unit;

a step B of obtaining a support member by a disassembling method according to claim 11;

and

a step of combining the image display unit prepared in said step A and the support member obtained in said step B.

19. A method for producing an image display apparatus, comprising:

a step A of preparing a support member;

a step B of obtaining an image display unit by a disassembling method according to claim 11;

and

a step of combining the support member prepared in said step A and the image display unit obtained in said step B.

21. A method for producing an image display apparatus, comprising:

a step of obtaining an image display unit and a support member by a disassembling method according to claim 11;

and

a step of combining said image display unit and said support member obtained in said step.

23. A method for producing a working material, comprising:

a step of obtaining a support member by a disassembling method according to claim 11;

and

a step of rendering the support member obtained by said step easily workable.

12. A method for producing a support member, comprising:

a step of separating, in an image display apparatus in which an image display unit including an internal space and a support member for supporting the image display unit are adhered by an adhesive member, said image display unit and said support member, wherein said separating step includes a step of inserting a substance between said image display unit and said support member.

13. A method for producing an image display unit, comprising:

a step of separating, in an image display apparatus in which an image display unit including an internal space and a support member for supporting the image display unit are adhered by an adhesive member, said image display unit and said support member, wherein said separating step includes a step of inserting a substance between said image display unit and said support member.

14. A method for producing a support member, comprising:

a step of separating, in an image display apparatus in which an image display unit and a support member for supporting the image display unit are adhered by an adhesive member, said image display unit and said support member, wherein said separating step includes a step of pressing said image display unit in a direction separating from said support member, through an aperture formed in said support member from a surface thereof opposed to said image display unit to a surface at the opposite side.

15. A method for producing an image display unit, comprising:

a step of separating, in an image display apparatus in which an image display unit and a support member for supporting the image display unit are adhered by an adhesive member, said image display unit and said support member, wherein said separating step includes a step of pressing said image display unit in a direction separating from said support member, through an aperture formed in said support member from a surface thereof opposed to said image display unit to a surface at the opposite side.
