Abstract: A display device includes a display panel having a display area and a non-display area and a polyimide substrate. The display device includes a transistor disposed above the substrate in the display area, a flexible film disposed on a side surface of the non-display area and connected to the substrate, and a conductive layer disposed below the substrate and applied with a low potential power voltage from the flexible film to improve an edge burn-in due to the polarization by offsetting positive charges in the polyimide substrate.
