## Abstract

An electronic device is provided. The electronic device includes a substrate having an edge and a peripheral area adjacent to the edge, a first inorganic insulating layer disposed on the first substrate, an organic insulating layer disposed on the first inorganic insulating layer and including a recess in the peripheral area, and a second inorganic insulating layer disposed on the organic insulating layer and in the recess. In a top view, the recess extends in a first direction parallel to the edge of the substrate. In a cross-sectional view, the recess has a bottom portion adjacent to the substrate, and a width of the bottom portion of the recess is greater than a thickness of the organic insulating layer.

## Claims

### Claim 1

An electronic device, comprising:
a substrate comprising an edge and a peripheral area adjacent to the edge;
a first inorganic insulating layer disposed on the substrate;
an organic insulating layer disposed on the first inorganic insulating layer, and having a recess in the peripheral area, wherein in a top view, the recess extends in a first direction parallel to the edge of the substrate; and
a second inorganic insulating layer disposed on the organic insulating layer and in the recess,
wherein in a cross-sectional view, the recess has a bottom portion adjacent to the substrate, and a width of the bottom portion of the recess is greater than a thickness of the organic insulating layer.

### Claim 2 (depends on 1)

The electronic device as claimed in claim 1, wherein the organic insulating layer has another recess in the peripheral area, and the another recess is located between the recess and the edge of the substrate.

### Claim 3 (depends on 2)

The electronic device as claimed in claim 2, wherein the another recess extends in the first direction, and in the cross-sectional view, the another recess has another bottom portion, and a width of the another bottom portion of the another recess is greater than the thickness of the organic insulating layer.

### Claim 4 (depends on 1)

The electronic device as claimed in claim 1, further comprising a metal layer disposed in the recess.

### Claim 5 (depends on 1)

The electronic device as claimed in claim 1, further comprising an organic material disposed in the recess, wherein the second inorganic insulating layer is located between the organic insulating layer and the organic material.

### Claim 6 (depends on 1)

The electronic device as claimed in claim 1, wherein the second inorganic insulating layer comprises an inorganic layer and an alignment layer.

### Claim 7 (depends on 1)

The electronic device as claimed in claim 1, wherein a thickness of the second inorganic insulating layer is less than the thickness of the organic insulating layer.
