Abstract: A display device includes: a base layer having a display area and a non-display area adjacent to the display area; a display element layer including a plurality of light emitting elements overlapping the display area; an encapsulation layer on the display element layer; a first dam in the non-display area; and a second dam in the non-display area and spaced apart from the first dam in a direction away from the display area from a boundary between the display area and the non-display area. An inorganic layer area is defined between the first dam and the second dam, and a groove is defined in the inorganic layer area.

Abstract: A display device includes a display area containing multiple pixels, and a pad area outside the display area containing multiple pads. The pads include a first conductive layer on the substrate, a second conductive layer above the first conductive layer, a third conductive layer above the second conductive layer, and a fourth conductive layer above the third conductive layer. The third conductive layer covers the side of the second conductive layer, and the display area includes multiple pixel electrodes, a fifth conductive layer located on the same layer as the third conductive layer, and a first insulating layer located between the fifth conductive layer and the pixel electrodes. No insulating layer is on the same layer as the first insulating layer between the third conductive layer and the fourth conductive layer of the pads, and the side of the third conductive layer has a smooth surface.
