In particular, unlike the display device of FIG. 2, the display device of FIG. 8 further includes a light emission control driver 60 in addition to a display portion 10 that includes a plurality of pixels PX, a scan driver 20, a data driver 30, a power supply 40, and a controller 50.

The light emission control driver 60 is connected to a plurality of light emission control lines EM1 to EMn that are connected to the plurality of pixels PX. That is, the plurality of light emission control lines EM1 to EMn that extend substantially parallel to each other while opposing the plurality of pixels PX in an approximately row direction connect the plurality of pixels PX and the light emission control driver 60.

The light emission control driver 60 generates a light emission control signal that corresponds to each pixel, and transmits the generated light emission control signal to the corresponding pixel through the plurality of light emission control lines EM1 to EMn. Each pixel PX which has received the light emission control signal is controlled to emit light according to a level of the light emission control signal. That is, an operation of a light emission control transistor included in each pixel PX is controlled in response to the light emission control signal transmitted through a corresponding light emission control line, and accordingly, an organic light emitting diode OLED connected with the light emission control transistor may or may not emit light with luminance according to a driving current that corresponds to a data signal.
