DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME

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.
