Abstract
A display device and a manufacturing method thereof are provided. The display device includes a display area, a non-display area surrounding the display area, a thin film transistor structure layer, a ring-shaped metal layer, a luminous layer, and a first electrode. The ring-shaped metal layer is disposed in the non-display area. The thin film transistor structure layer includes a passivation layer including a protrusion corresponding to the ring-shaped metal layer. The first electrode extends from the display area to the protrusion, and extends from a surface of the protrusion to a surface of the ring-shaped metal layer.
