Abstract: A display device includes: a substrate including a display area, a non-display area, and a sub-region, a circuit layer, a light emitting element layer, an encapsulation layer, and a polarization layer. The non-display area includes a dam area apart from the display area and in which at least one dam portion surrounding the display area is arranged, and a junction area surrounding the dam area. The circuit layer includes a semiconductor layer, a first insulating layer, a first conductive layer, a second insulating layer, a second conductive layer, a third insulating layer, a third conductive layer, a fourth insulating layer, and a fourth conductive layer. In the junction area, the encapsulation layer is disposed on the third insulating layer. A thickness of the third insulating layer at a central point of the junction area is substantially the same as a thickness of the third insulating layer in the display 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.
