Abstract
An organic light emitting diode (OLED) display device including a base substrate having a display area and a non-display area; OLEDs formed in corresponding sub-pixel regions defined by a bank insulating film in the display area of the base substrate; a pad part formed in the non-display area of the base substrate and configured to apply a driving signal to the OLEDs; a plurality of passivation films formed in the display area to cover the OLEDs, the plurality of passivation films including a first inorganic film, an organic film, and a second inorganic film, the plurality of passivation films being sequentially stacked. A region of an edge of the organic film that corresponds to a wire through which the driving signal is applied to the OLEDs from the pad part includes at least one groove formed at an inside area of the organic film.
