A display device includes a transistor including an active layer and a gate electrode which overlaps a channel region of the active layer and includes at least one layer, a storage capacitor which includes a first capacitor electrode which is electrically connected to the transistor and disposed below the active layer and a second capacitor electrode over the first capacitor electrode, a connection layer connecting the second capacitor electrode and the active layer to each other, and a conductive pattern disposed between the storage capacitor and the transistor and including a material identical to a material of the at least one layer of the gate electrode.
