Signal control unit for an organic light emitting diode display device, method of manufacturing the same, and organic light emitting diode display device including the same
A signal control unit for an organic light emitting diode (OLED) display device, includes a substrate structure including a plurality of active elements each corresponding to a pixel, a lower metal pattern disposed on the substrate structure, and electrically connected to a portion of the plurality of active elements, an insulating interlayer disposed on the substrate structure and at least partially covering the lower metal pattern, a via contact penetrating through the insulating interlayer and connected to the lower metal pattern, a metal electrode disposed on the insulating interlayer, and connected to the via contact, and an electrode passivation layer pattern substantially covering the metal electrode to expose a center portion of an upper surface of the metal electrode while covering a remainder of the upper surface and a side surface of the metal electrode. Therefore, leakage current which flows through the side surface of the metal electrode is suppressed.
