Claim 0:
1. A method of manufacturing a display device, the method comprising:
providing a thin film transistor on a light-emitting area of a substrate;
providing a first organic material layer covering the thin film transistor, and patterning the first organic material layer to provide a first insulating layer;
providing a pixel electrode electrically connected to the thin film transistor; and
providing a second organic material layer covering the first insulating layer and the pixel electrode, and patterning the second organic material layer to provide a second insulating layer which defines the light-emitting area,
wherein
the first insulating layer comprises:
a first area corresponding to the light-emitting area, and
a second area disposed outside the light-emitting area, the second area having a thickness which is less than a thickness of the first area,

within the light-emitting area, the second insulating layer covers edges of the pixel electrode and covers external lateral surfaces of the first area of the first insulating layer, and
a height of the second insulating layer decreases along a direction from the first area to the second area.
