Abstract
Embodiments of the disclosure are related to display devices, a planarization layer disposed on a thin film transistor in a display panel is removed to form an opening in the planarization layer, and a top gate electrode is disposed in the opening of the planarization layer, thus a driving performance of the thin film transistor is enhanced while reducing a size of the thin film transistor disposed in the display panel. Furthermore, the top gate electrode is implemented using an electrode layer located on an upper layer of the planarization layer, the thin film transistor including double gate electrodes is implemented easily without an additional process.
