The display apparatus may include gate lines passing through a display area of a substrate, data lines passing through the display area of the substrate, pixel driving power lines passing through the display area of the substrate, a plurality of pixels having a pixel driving chip mounted on at least one pixel area defined on the substrate and connected and connected to an adjacent gate line and data line and a light emission part connected to the pixel driving chip, a gate driving chip array part mounted in a non-display area of the substrate and connected to the gate lines, and a data driving chip array part mounted in the non-display area of the substrate and connected to the data lines.
