Display apparatus and method of manufacturing the same

A method of manufacturing a display apparatus, the method comprising:

• on a substrate, forming a first semiconductor layer and a second semiconductor layer for a first pixel and a second pixel, respectively;
• forming a first data line, the first data line including a first conduction line and a first transmission line, and the first transmission line electrically connected to the first conduction line, and the first conduction line is positioned between the substrate and the first transmission line;
• forming a second data line, the second data line including a second conduction line and a second transmission line, and the second transmission line electrically connected to the second conduction line, and the second conduction line is positioned between the substrate and the second transmission line;
• forming a first gate insulating layer and a first gate electrode on the first semiconductor layer;
• forming a second gate insulating layer and a second gate electrode on the second semiconductor layer;
• and
• forming an interlayer insulating layer covering the first gate electrode and the second gate electrode,
• wherein the first data line is configured to transfer a first data signal to the first pixel via the first transmission line, and wherein the second data line is configured to transfer a second data signal to the second pixel via the second conduction line.
