Abstract
A display device includes a light-emitting element on a light-emitting area of a substrate; a thin film transistor connected to the light-emitting element; a first insulating layer between the light-emitting element and the thin film transistor; and a second insulating layer which defines the light-emitting area and is between the thin film transistor and the second insulating layer. The first insulating layer includes a first area corresponding to the light-emitting area and a second area outside the light-emitting area, the first area has a first thickness, and the second area has a second thickness which is less than the first thickness, in a same one light-emitting area, the second insulating layer covers a lateral surface 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.
