Abstract
A display device can include multiple layers, and a capacitor on the multiple layers. The capacitor can include one capacitor electrode and the other capacitor electrode, in which the one capacitor electrode is on a layer where a first gate electrode of a first thin film transistor is disposed on, and an electrode disposed on a layer where the other capacitor electrode is disposed on and made of same material with the other capacitor electrode overlaps a second thin film transistor. The display device can further include a first planarization layer and a second planarization layer on the first thin film transistor and the second thin film transistor, and a source electrode of the first thin film transistor between the first and second planarization layers.
