Organic light emitting diode display

An organic light emitting diode (OLED) display comprising:

• a flexible substrate;
• a barrier layer disposed on the flexible substrate;
• a buffer layer disposed on the barrier layer;
• a thin film transistor disposed on the buffer layer;
• a capacitor disposed on the buffer layer;
• a passivation layer disposed on the thin film transistor and the capacitor;
• an organic light emitting diode disposed on the passivation layer, wherein the organic light emitting diode is electrically connected with the thin film transistor;
• and
• a thin film encapsulation layer encapsulating the organic light emitting diode, wherein the thin film encapsulation film includes a plurality of organic layers and a plurality of inorganic layers alternately stacked with each other on the organic light emitting diode,
• wherein the barrier layer includes a plurality of metal layers and a plurality of insulation layers which are alternatively stacked with each other on the flexible substrate, wherein an uppermost one of the insulation layers contacts the buffer layer and a lowermost one of the insulation layers contacts the flexible substrate.
