1. A display device, comprising:
multiple layers;
a capacitor on the multiple layers, wherein the capacitor includes one capacitor electrode and another capacitor electrode, wherein the one capacitor electrode is on a layer where a first gate electrode of a first thin film transistor is disposed on, and wherein an electrode disposed on a layer where the another capacitor electrode is disposed on and made of same material with the another capacitor electrode overlaps a second thin film transistor;
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 planarization layer and the second planarization layer,
wherein electrode patterns are disposed under the first planarization layer, and at least one of the electrode patterns is connected to the source electrode, and other one of the electrode patterns is connected to one of the one capacitor electrode and the another capacitor electrode.
