A display device includes: a substrate; a data line disposed on the substrate, the data line extending in a first direction; a gate insulating layer disposed on the data line; a gate line disposed on the gate insulating layer, the gate line extending in a second direction intersecting the first direction; a gate electrode protruding from the gate line; a thin film transistor connected to the gate line and the data line; and a first shielding electrode disposed on the same layer as a layer on which the gate line is disposed, the first shielding electrode overlapping the data line.
