Abstract: Discussed are an organic light emitting diode (OLED) display device and a method for driving the same. The OLED display device includes pixels each including a light emitting element, and a pixel driving circuit. The pixel driving circuit includes a driving switching element connected in series between high and low-level voltage supply lines, together with the light emitting element, a first switching element for connecting a data line and a first node connected to a gate of the driving switching element in response to a first scan signal, a second switching element for connecting an initialization voltage supply line and a second node connected to a source of the driving switching element in response to a second scan signal, and a third switching element for connecting the high-level voltage supply line and a drain of the driving switching element in response to an emission signal.
