1. A display device comprising:
a gate line extended in a first direction and a data line extended in a second direction crossing the first direction on a substrate;
a first switching element comprising a first source electrode connected from the data line, a first drain electrode spaced apart from the first source electrode, and a first gate electrode connected to the gate line; and
a second switching element comprising a second source electrode connected to the data line, a second drain electrode spaced apart from the second source electrode, and a second gate electrode connected to the gate line
a storage line disposed in parallel with the gate line;
a third switching element comprising a third source electrode connected from the storage line;
a third drain electrode spaced apart from the third source electrode; and
a third gate electrode connected to the gate line,
wherein a region of the first drain electrode overlapping the first gate electrode is extended in the second direction,
wherein the second source electrode is extended in the second direction, and is disposed in parallel with the first drain electrode and the second drain electrode,
wherein a region of the second drain electrode overlapping the second gate electrode includes a first region extended in the first direction and a second region extended in the second direction, and
wherein the third drain electrode is directly connected to the second drain electrode, and wherein the third source electrode and the second region of the second drain electrode face each other and arranged in parallel.
