A display device includes an active pattern, a gate electrode, a gate signal line, and a light emitting diode. The active pattern is disposed on a substrate. The gate electrode is disposed on the active pattern and overlaps the active pattern in a plan view. The gate electrode defines a channel area in an area overlapping the active pattern in a plan view. The gate signal line is disposed on the gate electrode. The gate signal line overlaps the channel area in a plan view. The gate signal line transmits a gate signal to the gate electrode. The light emitting diode is disposed on the gate signal line.
