Abstract
An organic light emitting diode (OLED) display device for simplifying a structure of an internal compensation pixel circuit is disclosed. The OLED display device is configured in such a way that an Npixel circuit shares a transistor for initializing a storage capacitor and a gate electrode of a driving transistor that belong to an (N+1)pixel circuit to initialize an OLED element. Accordingly, a transistor for initializing an OLED element is omitted from each pixel circuit, thereby simplifying a circuit structure and reducing a circuit area.
