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.

Abstract: A light emitting display apparatus includes a pixel driving circuit including a driving transistor and an anode reset capacitor connected to a gate of the driving transistor and a light emitting device configured to emit light with a current supplied through the driving transistor. An anode reset period, where a data voltage is not supplied to the driving transistor, is between refresh periods where the light emitting device emits the light with the data voltage supplied to the driving transistor, and an anode reset voltage supplied to the anode reset capacitor in the refresh period is higher than an initial voltage which is input to the gate of the driving transistor in the refresh period.
