Abstract:
1. An organic light emitting diode (OLED) display, comprising: a substrate; an organic light emitting diode on the substrate; a thin film encapsulation layer encapsulating the organic light emitting diode with the substrate, and including a plurality of organic layers and a plurality of inorganic layers alternately arranged with each other; an optical film on the thin film encapsulation layer and including an adhesive layer opposite to the thin film encapsulation layer; and a contamination preventing layer between the thin film encapsulation layer and the adhesive layer, wherein the contamination preventing layer directly contacts the thin film encapsulation layer and the adhesive layer, and the contamination preventing layer has a weaker adherence to the adhesive layer relative to an adherence between the thin film encapsulation layer and the adhesive layer, and wherein one of the plurality of the inorganic layers directly contacts the contamination preventing layer.
