Organic light emitting diode display

An organic light emitting diode (OLED) display, comprising:

• a substrate;
• a display portion on the substrate, the display portion including a common electrode and a common power line;
• and
• a sealing substrate fixed on the substrate and sealingly engaging the display portion, the sealing substrate being fixed by an adhesive layer that surrounds the display portion, wherein the sealing substrate includes:
• a composite member, the composite member including a resin base layer and a plurality of carbon fibers;
• a first conductive portion extending over inner and outer sides of the composite member and penetrating the composite member, the first conductive portion being connected to the common electrode to supply a first electric signal;
• a second conductive portion extending over the inner and outer sides of the composite member and penetrating the composite member, the second conductive portion being connected to the common power line to supply a second electric signal, each of the first and second conductive portions having of a double-layered structure having a metal foil layer and a plating layer;
• and
• an insulation sheet on the outer side of the composite member, the insulation sheet covering the first and second conductive portions.
