Abstract
A display device including a substrate, a buffer layer, an amorphous silicon layer, a first light blocking layer, a driving transistor, an upper capacitor electrode, a first switching transistor, a lower electrode, a light emitting layer, and an upper electrode. The driving transistor is disposed on a buffer layer under which a first light blocking layer is located and includes a first active layer including polysilicon and a first gate electrode disposed on the first active layer. An upper capacitor electrode is disposed on the first gate electrode and includes a metal oxide semiconductor. The upper capacitor electrode constitutes a capacitor together with the first gate electrode.
