Abstract

In a display device having high reliability, even if being a narrow framing type, and a method for manufacturing thereof, having a display panel, being made up with a first substrate 101 and a second substrate 201 , which are adhered with using a seal 301 , a main SOC 302 is disposed like a wall, on a peripheral end portion of the first substrate 101 and the second substrate 201 , and the seal 301 is disposed inwardly of the main SOC 302 . Also, in a method for manufacturing thereof, the main SOC 302 is formed in a region including a cutting plane between the display panel regions neighboring with, and on the cutting plane is made the cutting thereof.

First claim

What is claimed is:

1. A display device comprising:
a first substrate including a glass substrate, a first film, a second film, a first wiring, and a second wiring;
a second substrate opposing the first substrate; and
a seal between the first substrate and the second substrate,
wherein
the first film is between the glass substrate and the second film,
the first wiring is between the glass substrate and the first film,
the second wiring is between the first film and the second film,
the second film has a groove,
the groove overlaps the seal,
each of the first wiring and the second wiring overlaps the seal, and
each of the first wiring and the second wiring does not overlap the groove.

2. The display device of claim 1 , wherein
the first substrate further includes a pixel region inside of the seal,
the glass substrate has a first outside edge,
the groove is located between the first outside edge of the glass substrate and the pixel region, and
the first wiring and the second wiring are located between the groove and the pixel region.

3. The display device of claim 2 , wherein the second film is an organic passivation film.

4. The display device of claim 3 , wherein
the first substrate further includes a first alignment film, and
the first alignment film overlaps the outside edge of the glass substrate.

5. The display device of claim 3 , wherein
the second substrate includes a spacer,
the spacer has a cutting plane, and
the cutting plane of the spacer overlaps the outside edge of the glass substrate.

6. The display device of claim 5 , wherein
the groove of the second film is located between the spacer and the display region,
the spacer does not overlap each of the first wiring and the second wiring,
the groove does not overlap the spacer,
the spacer has a side surface opposed to the cutting plane, and
the side surface of the spacer is in contact with the seal.

7. The display device of claim 3 , wherein
the second substrate includes black matrix,
the black matrix overlaps the first wiring and the second wiring, and
the black matrix does not overlap the groove.

8. The display device of claim 5 , wherein
the second substrate further includes black matrix,
the black matrix overlaps the first wiring and the second wiring, and
the black matrix does not overlap the groove.

9. The display device of claim 5 , wherein the spacer does not overlap the black matrix.

10. The display device of claim 3 , wherein
the groove does not overlap the outside edge of the glass substrate, and
the second film overlaps the outside edge of the glass substrate.

11. The display device of claim 4 , wherein
the second substrate includes a spacer,
the spacer has a cutting plane, and
the cutting plane of the spacer overlaps the outside edge of the glass substrate.

12. The display device of claim 11 , wherein
a top surface of the spacer is in contact with the alignment film of the first substrate.

13. The display device of claim 1 , wherein
the first wiring is a gate wiring, and
the second wiring is a drain wiring.

14. The display device of claim 1 , wherein
the groove has a plurality of grooves at least two or more, and
the plurality of grooves do not overlap the first wiring and the second wiring.
