Abstract:
A display device includes a plurality of pixels respectively coupled to first scan lines, second scan lines and data lines; and a scan driver to supply first scan signals to the first scan lines and second scan signals to the second scan lines, wherein the pixel includes a first transistor having a gate electrode connected to a first node, one electrode connected to a first power line, and other electrode connected to a second node; a second transistor having a gate electrode connected to a first scan line, one electrode connected to a data line, and other electrode connected to the first node, the second transistor being turned on in a first time period of a frame when the first scan signal is applied; a third transistor having a gate electrode connected to a second scan line, one electrode connected to the second node, and other electrode connected to an initialization line, the third transistor being turned on in the first time period and at least one second time period of the frame when the second scan signal is applied; a storage capacitor having one electrode connected to the first node and other electrode connected to the second node; and a light emitting diode having an anode connected to the second node and a cathode connected to a second power line, wherein the number of the first and second scan signals applied to the pixel during the frame period is different from each other.
