A display device includes a substrate including a display area and a peripheral area. A display element is disposed in the display area and is electrically connected to a thin film transistor. A power supply line is disposed in the peripheral area. An insulating layer covers a portion of the power supply line. A barrier layer is disposed on the insulating layer and includes a first side surface facing the display area and a second side surface facing away from the display area. At least one of the first side surface or the second side surface includes a concavo-convex surface. The barrier layer forms a step difference with respect to an upper surface of the insulating layer. An end of the insulating layer is positioned beyond the second side surface of the barrier layer on a side of the barrier layer facing away from the display area.

Display device including a barrier layer with a concavo-convex side surface

A display device includes a substrate including a display area and a peripheral area surrounding the display area; a display element in the display area and electrically connected to a thin film transistor; a power supply line in the peripheral area; an insulating layer covering a portion of the power supply line; and a barrier layer on the insulating layer and including a first side surface facing the display area and a second side surface that is opposite to the first side surface, wherein at least one of the first side surface and the second side surface includes a concavo-convex surface, wherein the barrier layer forms a step difference with respect to an upper surface of the insulating layer, and an end of the insulating layer extends from the display area in a direction toward an edge of the substrate beyond the second side surface of the barrier layer.
