Abstract: Provided is a display device including a substrate, a circuit layer disposed on a first surface of the substrate, a light emitting element layer, and a circuit board disposed on a second surface of the substrate. The circuit layer includes pixel drivers, gate lines, a first power supply line and a second power supply line respectively transmitting a first power and a second power, and a gate driver including stages electrically connected to the gate lines, respectively. The second power supply line is electrically connected to the circuit board through power connection portions. The power connection portions are disposed between a number of the stages adjacent to a curved corner of the substrate among the stages of the gate driver.

Abstract: An emission driver includes stages including a first group of stages. Each of the stages of the first group among the stages include a first carry signal output component that outputs a carry signal having a turn-on level based on a voltage of a first node, and outputs the carry signal having a turn-off level based on a voltage of a second node; a first emission signal output component that outputs an emission signal having a turn-on level based on the voltage of the first node, and outputs the emission signal having a turn-off level based on the voltage of the second node; a first node voltage setting component that sets the voltage of the first node; and a second node voltage setting component that sets the voltage of the second node.
