1. A display device comprising:
a display panel including an active region and a peripheral region adjacent to the active region; and
a driver chip mounted on the display panel,
wherein the display panel includes:
a base layer;
a plurality of pixels disposed in the active region;
a plurality of data lines electrically connected with the plurality of pixels and configured to extend to the driver chip;
a plurality of sensors disposed in the active region;
a plurality of readout lines electrically connected with the plurality of sensors and configured to extend from the active region to the driver chip; and
a conductive layer disposed in the peripheral region and between one or more of the plurality of data lines and one or more of the plurality of readout lines,
wherein each of the plurality of pixels includes a pixel drive circuit comprising a transistor that includes a gate electrode disposed on a first layer above the base layer, a first connection electrode disposed on a second layer above the first layer and electrically connected to the pixel drive circuit, a second connection electrode disposed on a third layer above the second layer and connected to the first connection electrode, and a light-emitting element disposed on a fourth layer above the third layer and connected to the second connection electrode,
wherein the plurality of data lines are disposed on the first layer, which is same as the gate electrode, the plurality of readout lines are disposed on the third layer, which is same as the second connection electrode, and the conductive layer is disposed on the second layer, which is same as the first connection electrode, and
wherein the first layer, the second layer, and the third layer are disposed between the base layer and the fourth layer.
