A pixel set may include the following elements: a first diode for emitting first light of first color in a first time period; a second diode for emitting second light of second color in a second time period not overlapping the first time period; a first driving transistor for controlling electrical connection between a first power supply line and the first diode; a second driving transistor for controlling electrical connection between a second power supply line and the second diode; and a data transistor for transmitting a data voltage to a gate electrode of the first driving transistor and a gate electrode of the second driving transistor in response to a scan signal.
