Display device

1. A display device 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;

a first dam over the peripheral region and surrounding the display region; and

a second dam surrounding the first dam, wherein

the second layer is selectively arranged in a region surrounded by the first dam,

the resin layer entirely covers the display region and continuously extends from the display region to over the first dam,

an edge of the first layer, an edge of the third layer, and an edge of the resin layer are in alignment with one another directly above the second dam, and

the resin layer does not continuously extend outside the edge of the first layer or the edge of the third layer.

2. The display device according to claim 1 ,

wherein the pixel comprises:

a transistor;

a leveling film over the transistor; and

a light-emitting element over the leveling film,

wherein the first dam and the second dam exist in the same layer as the leveling film, and

the first dam, the second dam, and the leveling film are spaced from one another.

3. The display device according to claim 2 , further comprising a partition wall,

wherein the light-emitting element comprises:

a pixel electrode;

an organic layer over the pixel electrode; and

an opposing electrode over the organic layer, and

the partition wall covers an edge portion of the pixel electrode and the first dam.

4. The display device according to claim 3 , further comprising an auxiliary wiring over the peripheral region, the auxiliary wiring existing in the same layer as the pixel electrode,

wherein the partition wall has an opening overlapping with the auxiliary wiring, and

the opposing electrode and the auxiliary wiring are electrically connected to each other in the opening.

5. The display device according to claim 1 , further comprising an auxiliary wiring and terminals, wherein

the pixel comprises a light-emitting element having a pixel electrode, an organic layer over the pixel electrode, and an opposing electrode covering the organic layer, and

the auxiliary wiring surrounds the display region and extends between the display region and the terminals.

6. The display device according to claim 4 , wherein

the pixel electrode and the auxiliary wiring have the same stacked-layer structure.

7. The display device according to claim 5 , wherein

the pixel electrode and the auxiliary wiring have the same stacked-layer structure.
