Abstract: A display apparatus includes a substrate, a first pixel, a second pixel, a first wire set, and a second wire set. The first pixel and the second pixel overlap the substrate and neighbor each other in a first direction. The first wire set extends in a second direction, includes a first conduction line and a first transmission line, and may transfer a first data signal. The first conduction line is positioned between the substrate and the first transmission line and is connected through the first transmission line to the first pixel. The second wire set extends in the second direction, includes a second conduction line and a second transmission line, and may transfer a second data signal. The second conduction line is positioned between the substrate and the second transmission line and electrically connects the second transmission line to the second pixel.
