## Abstract

Disclosed is a display device possessing: a substrate having a display region and a peripheral region surrounding the display region; a pixel over the display region; a passivation film over the pixel; a resin layer over the passivation film; a first dam over the peripheral region and surrounding the display region; and a second dam surrounding the first dam. The passivation film includes; a first layer containing an inorganic compound; a second layer over the first layer, the second layer containing an organic compound; and a third layer over the second layer, the third layer containing an inorganic compound. The second layer is selectively arranged in a region surrounded by the first dam. The resin layer is selectively arranged in a region surrounded by the second dam.

## Claims

### Claim 1

A display deice comprising:
a substrate having a display region and a peripheral region surrounding the display region;
a pixel over the display region;
a passivation film over the pixel, the passivation film including:
a first layer containing an inorganic compound;
a second layer over the first layer, the second layer containing an organic compound; and
a third layer over the second layer, the third layer containing an inorganic compound;
a resin layer over the passivation film; and
a first dam over the peripheral region and surrounding the display region,
wherein the second layer is selectively arranged in a region surrounded by the first dam,
an edge of the first layer, an edge of the third layer, and an edge of the resin layer are aligned directly above the first dam, and
the resin layer does not continuously extend outside the edge of the first layer or the edge of the third layer.

### Claim 2 (depends on 1)

The display device according to claim 1, further comprising a second dam surrounding the first dam, wherein
the first layer and the third layer do not overlap with the second dam.

### Claim 3 (depends on 2)

The display device according to claim 2, wherein
each of the first dam and the second dam comprises an organic insulating material, and
the first dam and the second dam are spaced apart from each other.

### Claim 4 (depends on 1)

The display device according to claim 1, wherein
the pixel includes a pixel electrode,
an edge of the pixel electrode is covered with a partition wall, and
the first dam is covered with another partition wall which is the same layer as the partition wall.
