A display device includes: a display panel including an active area to be slid in a first direction and a non-active area surrounding the active area; a plurality of pixels in the active area; and a first power supply to transfer a first power voltage to drive the plurality of pixels, wherein the active area includes: a first active area; and a second active area on one side of the first active area in the first direction and configured to be slid in the first direction, the first power supply includes: a first voltage bar on one side of the first active area in the non-active area in a second direction crossing the first direction; a second voltage bar spaced apart from one end of the first voltage bar in the first direction and on one side of the second active area in the non-active area in the second direction.

Display device

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.

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.
