1. A display device, comprising:
a gate line disposed on a substrate in a first direction;
a data line disposed in a second direction crossing the first direction;
a first thin film transistor including a first source electrode extending from the data line, and a first drain electrode spaced apart from the first source electrode;
a second thin film transistor including a second source electrode extending from the first source electrode, and a second drain electrode spaced apart from the second source electrode;
a third thin film transistor including a third drain electrode extending from the second drain electrode, and a third source electrode spaced apart from the third drain electrode;
a first sub-pixel electrode electrically connected to the first drain electrode through a first contact hole;
a first reference voltage line electrically connected to the third source electrode through a second contact hole;
a second sub-pixel electrode electrically connected to the second drain electrode through a third contact hole,
a first conductive pattern extending from the third source electrode to the second contact hole, and
wherein the gate line is positioned between the first contact hole and the third contact hole,
wherein the first contact hole is aligned with the second contact hole in the first direction and wherein the second contact hole is at least partially aligned with the third contact hole in the second direction.
