Abstract
Each of pixels of a display device includes: a light-emitting portion including first light-emitting devices that are connected in a forward direction between a first electrode and a second electrode and second light-emitting devices that are connected in a reverse direction between the first electrode and the second electrode; a pixel circuit configured to receive a data voltage in synchronization with a scan signal, generate a driving current based on the data voltage, and output the driving current to a first node; and a light-emitting circuit configured to be controlled by a control signal, provide the driving current to the first light-emitting devices during a first emission period, and provide the driving current to the second light-emitting devices during a second emission period.
