Abstract: A display apparatus includes a first transistor, a first data line, a second data line, a driving voltage line, and a first insulating layer. The first transistor includes a first semiconductor layer and a first gate electrode. The first semiconductor layer includes a source region and a drain region. The first data line is disposed at a left side of the first transistor, and the second data line is disposed at a right side of the first transistor. The driving voltage line at least partially overlaps the first data line and the second data line. The first insulating layer is disposed between the first data line and the driving voltage line and between the second data line and the driving voltage line.
