A display device including: a substrate; a gate line disposed on the substrate to transmit a gate signal; a first reference voltage line spaced apart from the gate line to transmit a reference voltage; a second reference voltage line disposed on the gate line and the first reference voltage line and electrically connected to the first reference voltage line; an insulating layer disposed on the second reference voltage line; and a pixel electrode layer disposed on the insulating layer, wherein the pixel electrode layer includes a first pixel electrode having a first sub-pixel electrode disposed at a first side with respect to the gate line and a second sub-pixel electrode disposed at a second side opposite to the first side with respect to the gate line, and the second reference voltage line may overlap the first pixel electrode and may cross the first pixel electrode.
