Abstract: A display apparatus includes a substrate, a first data line, a second data line, and a bridge line. The substrate includes a display area and a peripheral area outside the display area. The first data line is disposed over the substrate and crosses the display area. The second data line is disposed over the substrate and is disposed in a first direction from the first data line. The second data line crosses the display area. The bridge line includes one end electrically connected to the second data line and crosses, on a different layer from a layer on which the first data line is disposed, the first data line in the display area. A length of the first data line is greater than a length of the second data line.
