1. An electroluminescent display apparatus comprising:
a first semiconductor pattern disposed on a substrate, the first semiconductor pattern including a first channel region and a first conductive region which is a region other than the first channel region;
a first gate electrode overlapping the first channel region of the first semiconductor pattern with a first gate insulation layer therebetween;
a data line directly connected to the first conductive region of the first semiconductor pattern without a contact hole;
a first interlayer insulation layer covering the first semiconductor pattern and the first gate electrode;
a second semiconductor pattern disposed on the first interlayer insulation layer, the second semiconductor pattern including a second channel region and a second conductive region which is a region other than the second channel region; and
a second gate electrode overlapping the second channel region of the second semiconductor pattern with a second gate insulation layer therebetween,
wherein the first conductive region of the first semiconductor pattern partially overlaps the second conductive region of the second semiconductor pattern with the first interlayer insulation layer therebetween.
