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 includes a first edge;
a first film on the first substrate;
a second film on the first film;
a first wiring provided between the first substrate and the first film;
a second wiring provided between the first film and the second film; and
a seal on the second film,
wherein
the second film is an organic film, including a first groove and a second groove,
each of the first groove and the second groove overlaps the seal,
each of the first wiring and the second wiring overlaps the seal,
the second groove is located between the first groove and the first edge,
the first groove is located between the first wiring and the second groove, and
the first wiring is located between the second wiring and the first groove.

2. The display device of claim 1 , further comprising:
a second substrate, and
wherein the seal is provided between the second film and the second substrate.

3. The display device of claim 2 , further comprising:
a first spacer in the seal,
wherein the first spacer overlaps the first wiring and does not overlap the second wiring.

4. The display device of claim 1 , further comprising:
a first alignment film on the second film,
wherein
the first alignment film overlaps the seal, and
each of the first groove and the second groove is covered by the first alignment film.

5. The display device of claim 4 , wherein the first alignment film overlaps the first edge of the first substrate.

6. The display device of claim 1 , wherein
the second film further includes a third groove,
the third groove overlaps the seal, and
the third groove overlaps the first wiring and does not overlap the second wiring.
