Abstract: A display apparatus includes: a substrate comprising a display area and a peripheral area; a light-emitting diode in the display area on a front surface of the substrate; a driving transistor in the display area, electrically connected to the light-emitting diode, and comprising a silicon-based semiconductor layer; a switching transistor in the display area and configured to transmit a data voltage to the driving transistor; a compensation transistor in the display area, configured to diode-connect the driving transistor, and comprising an oxide-based semiconductor layer; a gate driving circuit in the peripheral area and electrically connected to the compensation transistor; and a first lower layer in the peripheral area and interposed between the substrate and the gate driving circuit.
