| Zusammenfassung: | According to the present invention, provided is a light emitting display device, which includes: a display panel configured to display an image; a driver configured to drive the display panel; a controller configured to control the driver; and a sensing circuit configured to sense a current through a driving voltage line transmitting a driving voltage for driving of the display panel, and output a sensing value, based on the current, for determining whether an element in a subpixel of the display panel is defective. Accordingly, the present invention improves afterimage and lifespan, production yield, reliability and stability.
