Display device

The display device includes a substrate including a display area and a non-display area adjacent to the display area; a buffer layer on the substrate; a metal layer disposed on the buffer layer in the non-display area; an insulating layer on the metal layer including a contact hole configured to expose the metal layer; a first planarization layer in the display area and the non-display area on the insulating layer; a second planarization layer on the insulating layer in the non-display area and spaced apart from the first planarization layer; a transparent conductive layer on the first planarization layer and the second planarization layer in the non-display area, electrically connected to the metal layer through a contact hole; a plurality of thin film transistors in the display area including a gate electrode, an active layer, a source electrode, and a drain electrode; and a plurality of light emitting diodes in the display area including an anode and a cathode, the cathode extending from the display area t
