    Abstract: A display device includes a display panel, a light emission control driver, and a brightness compensator. The display panel includes first pixels in a first display area and second pixels in a second display area. The light emission control driver controls light emission times of the first and second pixels. The brightness compensator detects a degree of deterioration of the first pixels and a degree of deterioration of the second pixels. The degrees of deterioration of the first and second pixels are different. The brightness compensator controls the light emission control driver to set the light emission times of the first pixels differently from the light emission times of the second pixels based on the different degrees of deterioration of the first and second pixels.

    Abstract: An organic light-emitting device is provided to have high efficiency and long lifespan. The organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; an emission layer disposed between the first electrode and the second electrode and including a host and a dopant; an electron blocking layer disposed between the first electrode and the emission layer; and an electron transport region disposed between the emission layer and the second electrode, in which the electron blocking layer includes a metal halide, a metal oxide, or a combination thereof, and the actually measured lowest unoccupied molecular orbital (LUMO) value of the electron blocking layer is greater than the actually measured LUMO value of the host in the emission layer.
