Abstract: A display device in one embodiment according to the present invention includes a first region including a light emitting layer, a first nitride insulating layer over the light emitting layer, a first organic insulating layer over the first nitride insulating layer, a second nitride insulating layer over the first organic insulating layer, and a third nitride insulating layer over the second nitride insulating layer. The second nitride insulating layer is in contact with the first organic insulating layer and the third nitride insulating layer. An absolute value of a stress of the second nitride insulating layer is greater than or equal to an absolute value of a stress of the first nitride insulating layer and less than an absolute value of a stress of the third nitride insulating layer.
