Abstract
Embodiments of the disclosure relate to a self-emission display device and a self-emission display panel and include a fake subpixel disposed in a non-display area of the self-emission display panel and including a reference transistor controlled by a control signal and connected between a first voltage node and a detection node and a bias transistor controlled by a bias voltage and connected between a second voltage node and the detection node. Thus, it is possible to restore the initial characteristic value of the driving transistor in the subpixel disposed in the display area by driving the fake subpixel.
