Abstract: Discussed is a display device including a substrate, semiconductor light-emitting elements on the substrate, flip-flops which can apply an electrical signal to the semiconductor light-emitting elements to maintain the semiconductor light-emitting elements in a light-emitting state for a predetermined time interval, scan electrodes and data electrodes electrically connected to the flip-flops, respectively, and a driver. When a frame synchronization signal is generated during a time interval from a time point of the generation of a sub field signal to a time point of the generation of a subsequent sub field signal, the driver can prevent a voltage from being applied to the data electrodes for the time interval.
