Abstract: Provided is a display panel to which a dual gate transistor is applied. The display panel includes a substrate including a pixel area and a non-pixel area and a dual gate transistor disposed on the non-pixel area. The dual gate transistor includes first and second transistors which are connected in series and an auxiliary electrode which connects two gate electrodes of the first and second transistors. The auxiliary electrode is on a layer which is different from the gate electrode. Therefore, an area in which the dual gate transistor is formed is reduced and stability of the driving circuit is secured.

Abstract: A display device in one embodiment includes a flexible substrate, a back plate disposed under the flexible substrate to support it, a conductive layer disposed on at least one surface of the back plate, and a printed circuit board connected to one side of the flexible substrate. The conductive layer is electrically connected to the printed circuit board and receives a constant voltage applied thereto. Therefore, by applying the constant voltage to the conductive layer, it is possible to reduce the polarization occurring on the flexible substrate.
