1. A display device, comprising:
a gate line and a storage line arranged on a substrate in a first direction and spaced apart from each other;
a data line and a partial voltage reference line arranged in a second direction crossing the first direction and spaced apart from each other;
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 and extending from the partial voltage reference line;
a color filter disposed on the first, second, and third thin film transistors and including a first via hole exposing the third source electrode and the third drain electrode; and
an insulating layer disposed on the color filter and including a first contact hole exposing the storage line and a second contact hole exposing the third drain electrode,
wherein the first contact hole and the second contact hole are disposed in the first via hole when viewed in plan.
