Manufacturing method for display using surface treatments of adhesion surfaces

1. A manufacturing method for a display in which a transparent plate is adhered to an outer surface of a screen provided on a display main body, comprising the steps of:

setting the outer surface of the screen of the display main body and one surface of the transparent plate as respective adhesion surfaces;

performing a surface treatment at a peripheral edge region of one or both of the adhesion surfaces such that a surface energy of the peripheral edge region is smaller than a surface energy of a remaining region of the two adhesion surfaces and a surface energy of an adhesive used in the adhesion;

disposing the display main body and the transparent plate such that the two adhesion surfaces oppose each other via a gap; and

injecting the adhesive into the gap,

wherein the surface treatment is performed within a width range of 1 mm to 3 mm from the edge regions of the adhesion surfaces.

2. The manufacturing method for a display according to claim 1 , wherein the surface treatment is performed on the peripheral edge regions of the two adhesion surfaces.

3. The manufacturing method for a display according to claim 1 , wherein the display main body and the transparent plate are disposed such that the two adhesion surfaces are vertical, and the adhesive is injected from an upper side of the gap.

4. The manufacturing method for a display according to claim 2 , wherein the display main body and the transparent plate are disposed such that the two adhesion surfaces are vertical, and the adhesive is injected from an upper side of the gap.

5. The manufacturing method for a display according to claim 2 , wherein a surface treatment is performed on side faces of the transparent plate and the outer surface of the screen.

6. A manufacturing method for a display in which a transparent plate is adhered to an outer surface of a screen provided on a display main body, comprising the steps of:

setting the outer surface of the screen of the display main body and one surface of the transparent plate as respective adhesion surfaces;

performing a surface treatment at a peripheral edge region of at least one of the adhesion surfaces such that a surface energy of the treated peripheral edge region is smaller than a surface energy of a remaining region of the two adhesion surfaces and a surface energy of an adhesive used in the adhesion;

disposing the display main body and the transparent plate such that the two adhesion surfaces oppose each other via a gap; and

injecting the adhesive into the gap.

7. The manufacturing method for a display according to claim 6 , wherein the surface treatment is performed on peripheral edge regions of the two adhesion surfaces.

8. The manufacturing method for a display according to claim 6 , wherein the display main body and the transparent plate are disposed such that the two adhesion surfaces are vertical, and the adhesive is injected from an upper side of the gap.

9. The manufacturing method for a display according to claim 7 , wherein the display main body and the transparent plate are disposed such that the two adhesion surfaces are vertical, and the adhesive is injected from an upper side of the gap.

10. The manufacturing method for a display according to claim 7 , wherein a surface treatment is performed on side faces of the transparent plate and the outer surface of the screen.
